Have an error here (alltrim(.t.)) ???

This code:
if lbValue
lcValue = "'Y'"
ELSE
lcValue = "'N'"
ENDIF

Show the same result in the whole column. So, I think now I can forget about this idea...

I don't want to create this for one single form, I want to provide this functionality for our classes - our base form and our navigation bar class.
