Dear Jack,

This forum is for Envision specific issues. If I could help you quickly I would, but I

cannot go into analyzing and debugging specific parts of code.

You should try and isolate your problem using the integrated debugger. Find at which point

you have the expected values by setting "watches" or evaluating variables. Then find at

which point the values in your variables are not what you expect.

Best regards,

Michel
