Menu Error

[NullOp]

I have an AR app written in FPW 2.6a.
When the user selects 'Branch' to select which dataset to work with they get an 'Operator/Operand Type Mismatch' error. They can then select 'Branch' again and everything is OK. Work continues normally.

This error never ocurrs on my PC, XP, 128 MB, 20 GB HD. Matter of fact it only occurs on users that actually use the program! I've installed the system on utility PCs and have not had the problem which is very frustrating from my point-of-view.

The error also bypasses the error handler that is in effect when it ocurrs, e.g. my error handler should give a wait window stating the error but this error is in a window at the bottom of the screen.

This is beginning to reach the upper end of my weird-problems-o-meter. Any ideas. I've been through the tracing routines, etc, etc.

Nullop,
1) not loaded variable is primarily logical
and usually first use caused ...mismatch operand.
2) check
on error
without good calling your error procedure.
May be missing modul with both loading variable
and setting error...

Hi Nullop,
Probably if you were to post some part of your code, you might get more solutions. whats the OS of the system where you get the error?

Make sure all your variables are initialized to at least the proper type before accessing them. If you've traced through it, you should be able to see a variable being used all of a sudden that previously had no value.
