Submit button of paypal form not working when form is embedded.

The link to PayPal is not working when embedded into a web page.  If I access the PayPal form directly it works but if I try to submit a form that has been embedded in a webpage it just hangs.

Here is the form:  https://form.jotform.com/61388562681970

Here is the form embedded in the website that doesn't work.

I checked your form and I can see that you are using Jotform oEmbed to embed the form to your page. There might be some conflict with the script on the page and jotform. To resolve the issue, please try embedding the form to your page using the iFrame embed code instead. You can get the iframe code by following this guide: Getting the Form iFrame Code.
If the issue persists, please let us know.
