I have a form that is used to create a credit memo. When the user types a valid invoice number on the main form a subform is populated showing all the line items on the invoice against which the credit will be applied. The user can then 2-click a line item and it will be added to the credit memo. This works fine on 15 computers on our LAN, but on one computer the subform fails to populate when the user types the invoice number. The users are all using an ACCDE front end that resides on thier PC and is linked the a back end that resides on our server. The subform is linked to the main form via the invoice number field. All users are using the Access run time 2010. Any suggestions?
