I have a subform that 3 Master/Child links such as Client, PaidDate and CheckNumber. After the main form is updated, the cursor will focus on a field in the subform and this subform will show the unpaid invoices belong to the current Client if the 3 mentioned criterias are not met. It worked perfectly until I formatted my computer and reinstalled everything, now it does not work anymore except when those 3 criterias are met (it shows that Client, PaidDate and CheckNumber). What gives ?
