Looks over complicated how about getvalue( substitute( _text;"|";"¶");_partNumber) extending that you could even included a parameter for the delimiter

Your solution is excellent Tim! It's very easy to understand exactly what it's doing, and is efficient also. The only drawback I can see to it is that it won't support parts that have hard-returns.

... and yours will not work if the pipe is part of the part number :-))

Touché Of course, this custom function does let you swap out the delimiter for any other character or set of characters you deem fit.

Ok, a solution PickAPart__cf ( _text ; _partNumber ; delimiter) let( _useText=case( delimiter="¶"; _text; substitute( _text;"¶"; "x§§x§§x"); substitute( getvalue( substitute( _useText ; delimiter ;"¶");_partNumber); "§§x§§";"¶") )
