No Duplicates for Combination of Fields for the Main Form

No Duplicates for Combination of Fields for the Main Form

Hi,

We can prevent duplicate entries of a subform using a combination of fields, but we can only do this with a single field on the main form.

I would like to be able to do the same on the Main Form under Form Settings or Deny Rules, and ideally also use Subform fields as well as Main Form fields in the combination.

Thanks

Dan
