    Hi guys,

    In my system to keep data consistent between switching tabs, I have a textbox I call. To populate a subform with the current record I link master fields 'txtMaterial' and this works. It populates the material number correctly from the corresponding record. However, I have 3 primary keys that need populated and I'm not sure what to type in the link master fields. So far I have tried txtMaterial;txtLocation;txtDelivery with child fields Material;Location;Delivery. However I get an error saying the setting you entered isn't valid for this property. Why does it work with one box, and not 3? If anyone knows a workaround I would be so appreciative thank you

    Also, if i try it with just two and not 3 I get the following error 'The expression is typed incorrectly, or it is too complex to be evaluated. For example, a numeric expression may contain too many complicated elements. Try simplifying the expression by assigning parts of the expression to variables."

    Can you provide a copy of the database with some dummy data?
    Or at least some screen shots of what you trying to achieve.
