>In getexpr if I use my own functions, like GetDescription(town,'towns','town','fullname') I always have an error: 'Invalid subscribe (?) reference' (or something similar). This Error could be ignored. Now is my question: how can I catch this error and in this case do nothing. All other errors should be treated as 'normal' errors.

Nadya,

If you are getting an error, something is wrong. It could be that GetDescription is an internal function used by VFP. I've seen this before. I had a function called IsLead that would give me a similar error.
