A quick function to return the index of the first value in 'values' that contains the search 'string'. If the string isn't found returns 0.

FirstMatchIndex ( "AlfredÂ¶BettyÂ¶FredÂ¶George" ; "Fred" ) returns 1 instead of the expected 3. This is because you're not testing for the position of the string as a value. Try instead: ValueCount ( Left ( values ; Position ( Â¶ & values & Â¶ ; Â¶ & string & Â¶ ; 1 ; 1 ) ) ) (from: http://www.briandunning.com/cf/908)

Err, no. If that's what you want, try https://www.briandunning.com/cf/2342 or https://www.briandunning.com/cf/2342 ; This function specifically is looking for a partial match. Returning 1 is precisely what "first value in 'values' that contains the search 'string'" is meant to mean - hence the 'contains'. ;-)
