I appreciate your reply.
Actually, I didn apply validation to the company_name field, rather, Validation Toolkit ignored the other fields I had selected to validate, and applied everything to the first field, which happens to be company_name. Correcting it and saving it as you described does not seem to fix it.
There is a bug in Validation Toolkit. I suspect that I have a field name that it does not like, and it breaks your code. When I get time, i will go back and isolate the bug.
