Rock,

The only thing that could possibly be causing an error
(Other than a data type mismatch) is that you are
relying on your design time constant beyond its scope.

Remember that a constant initialized with #DEFINE
is only known to the the form’s method in which
you DEFINEd it.

If you need it to be visible throughout your entire form,
you must put it in a separate file and link it to the
form by selecting "Include File" from the Form menu.
