Re: Field concatenation

Kevin, I think the OP meant something a bit different from your 
specification here - here's my understanding -

> blanks are placeholders and you need a single comma for each blank variable

This is very easily handled with a procedure (several have suggested 
using a procedure), maybe even the one I posted earlier, which returns 
either the passed value when not blank or a single comma when blank.
