Verify Function

I use various methods to verify text fields in my scripts successfully. Now, I'm trying to use the Verify function, but it's producing a NULL result.

This syntax is straight from the help file.

[ ] Verify(App.Dialog.Field.GetText (), "10", "selected text")
[ ] //--Result is null.


[ ] Print(App.Dialog.Field.GetText ())
[ ] //--Produces expected result

Simple enough, but what am I missing?
