Hello,

You can set your payment field as required so that form users will be compelled to select a product and make purchase on your form.

To do this:

1) Edit your form and select your payment field

2) Click the Required option on top 

Once the Required option is enabled, save your form. After which, from here moment on, your form should not submit without any selected product  in it.

If you have questions, please let us know.
