When running my program I get an invalid function message on this line:

Just use this:

if @dlgtext(Engines)

I think Mac meant:

If @ZERO(@dlgtext(Engines))

Actually I didn't - I was pointing out how to check for a value. Wink

If I was gonna check for a NULL value I'd use @not() anyway.

if @not(@dlgtext(Engines))

My bad, I assumed GeoTrail was checking to see if a value was zero.

Good point - he was trying to use @zero(). Wink

Actually. I wanted to use the ZERO function to see if the user selected an item in the combo. I might have misunderstood it's function Embarassed

Actually @zero() checks for a zero value, although it returns
FALSE if the value isn't zero.

@not() and @null() check for an empty (NULL) value to start with. Wink

Thanks Mac.
I tried the if @dlgtext(Engines) solution and it seems to work fine Smile
