The number of forms means how many Formidable Forms can be activated to merge data to any number of PDF forms.
The number of sites means how many sites the activation key will work on.
For your activation key you can request to mix and match your forms/sites… so for 1-Site | 10-Forms you could request us to change it to 5-Sites | 6-Forms… or any other combination.
We remain at your service.
