Question

Datagrid bound to filtered recordset

I have a calendar that plugs into an Access database. I am implementing a search feature that will allow users to display records in a datagrid.

I have filtered the recordset based on the form variable. It works fine, except, when I try to page through the datagrid it throws an error, or if I try to edit a record, I just get a blank record.

I can post the code if necessary, but I am assuming that I need to somehow save the variable...

Thanks in advance
