A & B are controls on a subform that get their data from other fields. A is from a total field on the subform's subform.
When I open the form for the first time All works well (Capture5.PNG)
When I duplicate all of the records in a project and move to the duplicate AB&C are correct but I get error in D. The really strange thing is that I now get the same error at D in ALL records including the original that was duplicated. When I close the form and reopen all records are correct including the duplicate.
I have tried refresh dirty update etc but the only way to get back to correct calculated fields (D) is to close the form and re-open. How can that be? It's as if duplicating the records has switched off certain calculates controls.
A. B, and C are all correct. D Gives error
