Text box on main form won't pick up value from field on subform

[Guest]

Text box on main form refers to field on subform (actually IDfield), should
pick up & display value in text box. No value - just blank. The same form
worked fine in previous versions of Access but when I converted my DB to
Access 2003, this text box no longer works!

The Subform may have many records; a mainform reference to a control on the
subform will refer to the "current" record on the subform, if any. If the
subform is currently pointing at the "new" record then this will be blank. How
do you want Access to decide which subform record should be relayed to the
mainform... and why?
