How to have a Feedback button embed

I am trying to use the Lightbox to hide my form and open with a "buy now" button however, Im looking at the Lightbox dialogue screen and don't see a "embed options" to choose a "feedback button".

The publish embed code for Feedback button and Lightbox code are 2 different thing.

I think what you want to have is the Feedback button.

You can have it by going to Publish / Embed / Feedback button

I want to use the Paypal button and link it to the jotform form. I am not getting specific instructions from you how to achieve this. I do not want the form to show on the website....I want it to appear after you click on "register/buy" button. I've already created the form. If you are not going to provide me with a "live" person, I need step by step instructions on how to do this. I don't understand your previous emails.

If you want to have your form submit to paypal payment, you need to use Paypal integration.
