Sergey:
You may be right, although I am confused. How would Hugo's code be able to handle the variables going out of scope any differently from my code?
My code is:
*********************************
...
CASE !EMPTY(ThisForm.txtFName.Value).and.!EMPTY(ThisForm.txtLName.Value)
lcLName = ThisForm.txtLName.Value
lcFName = ThisForm.txtFName.Value
SET FILTER TO UPPER(People.FName) = ALLTRIM(UPPER(lcFName));
.AND.UPPER(People.LName) = ALLTRIM(UPPER(lcLName))
...
*********************************
