I made a database to help the office girls with invoices that have to be written (multiple invoices same information). I created a duplicate button to copy my form and sub form onto a new record. The form copies over but the sub form append query comes back with the following error "The INSERT INTO statement containes the following unknown fieldname [Forms]![Orders].Tag" the tag refered to in the query is the Tag Property in the Orders Form. I've been away for awhile and access has moved on without me, I am getting back into it and would be very thankful for any assistance anyone can give.Thank You
