### Title

What is wrong with my Case calculation?

### Post

I'm writing a recursive calculation to look through the source code of a web page to find the book sellers that have the cheapest price. I want to exclude ourselves from the calculation. So I am using the PatternCount function and a Case function to keep moving through the booksellers who do not have one of our two names. Our names are Tolka Unused, Tolka Unused Books and Book-Fare. The cheapest price always comes at the top of the list. I want to isolate the price that is not our price that is the cheapest.

Let ( [
Seller1 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 1 ) ;
Seller2 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 2 ) ;
Seller3 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 3 ) ;
Seller4 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 4 ) ;
Seller5 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 5 ) ;
Seller6 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 6 ) ;
Seller7 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 7 ) ;
Seller8 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 8 ) ;
Seller9 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 9 ) ;
Seller10 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 10 ) ;
Seller11 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 11 ) ;
Seller12 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 12 ) ;
Seller13 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 13 ) ;
Seller14 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 14 ) ;
Seller15 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 15 ) ;
Seller16 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 16 ) ;
Seller17 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 17 ) ;
Seller18 = Parse ( Inventory::source_bookfinder ; "<tr valign=\"top\" class=\"results-table-LogoRow\" >" ; "onmouseover" ; 18 ) ;
Price1 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 1 ) ;
Price2 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 2 ) ;
Price3 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 3 ) ;
Price4 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 4 ) ;
Price5 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 5 ) ;
Price6 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 6 ) ;
Price7 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 7 ) ;
Price8 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 8 ) ;
Price9 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 9 ) ;
Price10 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 10 ) ;
Price11 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 11 ) ;
Price12 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 12 ) ;
Price13 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 13 ) ;
Price14 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 14 ) ;
Price15 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 15 ) ;
Price16 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 16 ) ;
Price17 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 17 ) ;
Price18 = Parse ( Inventory::source_bookfinder ; "26pound\x3b" ; "\\" ; 18 )
]
;
Case (
PatternCount ( Seller1 ; "Book-Fare")  or PatternCount ( Seller1 ; "Tolka") < 1 ; Price1 ;
PatternCount ( Seller2 ; "Book-Fare")  or PatternCount ( Seller2 ; "Tolka") < 1 ; Price2 ;
PatternCount ( Seller3 ; "Book-Fare")  or PatternCount ( Seller3 ; "Tolka") < 1 ; Price3 ;
PatternCount ( Seller4 ; "Book-Fare")  or PatternCount ( Seller4 ; "Tolka") < 1 ; Price4 ;
PatternCount ( Seller5 ; "Book-Fare")  or PatternCount ( Seller5 ; "Tolka") < 1 ; Price5 ;
PatternCount ( Seller6 ; "Book-Fare")  or PatternCount ( Seller6 ; "Tolka") < 1 ; Price6 ;
PatternCount ( Seller7 ; "Book-Fare")  or PatternCount ( Seller7 ; "Tolka") < 1 ; Price7 ;
PatternCount ( Seller8 ; "Book-Fare")  or PatternCount ( Seller8 ; "Tolka") < 1 ; Price8 ;
PatternCount ( Seller9 ; "Book-Fare")  or PatternCount ( Seller9 ; "Tolka") < 1 ; Price9 ;
PatternCount ( Seller10 ; "Book-Fare")  or PatternCount ( Seller10 ; "Tolka") < 1 ; Price10 ;
PatternCount ( Seller11 ; "Book-Fare")  or PatternCount ( Seller11 ; "Tolka") < 1 ; Price11 ;
PatternCount ( Seller12 ; "Book-Fare")  or PatternCount ( Seller12 ; "Tolka") < 1 ; Price12 ;
Price1
)
)

I want to use this

PatternCount ( Seller1 ; "Book-Fare")  or PatternCount ( Seller1 ; "Tolka") < 1 ; Price1

to choose Price1 if there is no "Book-Fare” or “Tolka” in the parsed text. But it is choosing Price1 even if "Book-Fare” or “Tolka” is in the parsed text. What is wrong with my Case calculation?

FYI here is the long html code which I am parsing:
