You don't really need the ' "¶" & $SearchString & "¶" ', though: just '$SearchString' will open your trick up to searching the entire line.
I made this modification and it's working for my purposes (isolating an entire line in html code (from a server) to be processed), thanks!
The leading and trailing returns are needed.
Otherwise, searching for a "4" in the above sample list will return a value instead of zero.
Oy! Apologies, then. I do have to search the entire line for an occurance, though: a way to go about that would be to search for a positive (or negative) for a 'Substitute()' (eventually replacing itself for a 'positive'), or something like that.
Um, again apologies because I've just understood that, unless specifically indicated (by using the MiddleValues function, etc.), lists will be treated as text (and the line returns as characters). I didn't realise this, and this understanding helps greatly (and opens new possibilities).
