>I can only get your first example to run if it's lcYourVariable not ?lcYourVariable, which is a requirement (I think) for Parameterized Views. I am trying to build a P-View giving VFP a substring to search instead of a standard "read left-to-right" search.

In that case, you would have percent signs in front and at the end of the string to search for. I do not know why you can not use the question mark. This is standard fare for those of us using parameterized views. It even works when all you pass is the percent sign.
