Please do post your own thread with details about your form(s), how they're being used and exactly what the issues are because this one is 10 years old. I also get the impression that your form is based on a query using 2 or more related tables, and that is probably your main problem. Typically it is a one form to one table (query) that should be created unless you are prepared to do a bit of coding to prevent issues. Or use temporary records in "temp" tables and copy over when all is done.
The more we hear silence, the more we begin to think about our value in this universe.
