Refresh an unbound field

[mrssevans]

I have an unbound field on a subform (Orders) that is refered to another subform (Payments). After updating the subform (Payments) I can't get the unbound field to update even when I use Me.Requery in several fields. These subforms are on a tab control. If I put a refresh button on the Orders subform it will work but can't find any code that will. Please help.
