Subform Entry Limit from a Subform Field (A different Subform on the same Form)

Subform Entry Limit from a Subform Field (A different Subform on the same Form)

Hi,

I would like to be able to use a Subform 1 Field as the Dynamic Entry Limit for Subform 2.

Even better would be able to use some code with the values, so for example using the Subform 1 Qty Field as the Max Entry limit for Subform 2, BUT only the Subform 1 Row's Qty Field Value where the Subform 1 Product Field is "ABC".

Thanks

Dan
