How can I add a PayPal button to my form?

I need to build a paypal form.

I have the HTML code for a PayPal button.  How can I add the button to my form?

Thanks for your help.

Unfortunately, adding PayPal button script to the form is not supported with JotForm. This is due to any scripts added to the form will be truncated due to security related issues. However, you may use the PayPal integration on the form so that you can receive the payments directly from the form.

Alternatively, you may consider downloading the source code of the form and add the PayPal button to the form. 

Thank you! 

Also, if the PayPal button is added using the script the form redirects to the PayPal to process the payment. But the form never submits and the form filled information will not be stored in your account.
