1) no. You might make a copy of your fields that already have conditional formatting, select the group of fields that should all get the same conditional formatting and then refer to the copies to copy and paste those expresssions back into additional formats for the individual fields where this is necessary. It may be less work to just apply the conditial formats separately to these fields instead of in a group.
2) IsEmpty ( valueListItems ( get ( FileName ) ; "YourValueListNameinQuotes" ) ; Shows::Rope Circle )
Could be used to assign a bright fill color or contrasting text color and/or style to draw attention to all such entries. You can also put that expression in a calculation field (clear the "do not evaluate if all referenced fields are empty" check box), if you want to search for all records where such a case is true. (Enter 1 as criteria in this field.)
Thanks for your answer.
That Funtion looks great but I am having an issue with getting it to work
I get the error message "There are too many parameters in this function."
This is how I have the formula in the conditional formatting box...
IsEmpty ( valueListItems ( get ( FileName ) ; "Boat" ) ; SHOWS::Rope Circle S)
IsEmpty ( FilterValues ( ValueListItems ( get ( FileName ) ; "Boat" ) ; SHOWS::Rope Circle S ) )
Thanks Guys, Much appreciated!
