Each option for the Checkout
will be suffixed by the order that it’s in on the form.
For the default example:
First Choice
would come through the entry as 1.1Second Choice
would come through the entry as 1.2Third Choice
would come through the entry as 1.3
If you choose to modify the order of the choices their entry reference would change as well.
Moving Second Choice
to the top position would them make it 1.1 and First Choice
to 1.2
