Hi
If I create a Form which allows you to select a Tag what data would you then want to be able to add?
The attached screenshot allows me to select a Tag, and then add details about a specific Level Transmitter and Pressure Transducer associated with the Tag selected.
From the Relationship diagram it is difficult to determine what in fact you need to do.
Do you want to be able to Select a Tag and then enter details of the Pressure Transducer as well as details of the Level Transmitter?
Hi Bob
Well Gasman gave you the solution as to how you can achieve this.
All I am trying to do is point out that the structure of the Subform is wrong.
So the Subform for entering Invoice Number information must be based on a query based on Multiple Tables.
The Subform has Multiple Redundant Controls because all you actually need to enter in the Subform is the "Date", "Invoice Number" & "Amount"
