How to add PayPal button to my JotForm?

I had one on there but it isn't working, please help

I have checked your JotForm and it seems that you are adding PayPal button script to the text area field. Unfortunately, the PayPal button script contains some javascript code and injecting Javascript codes to the form are not allowed with JotForm due to security reasons. Such scripts added to the form are automatically trimmed from the form. 

If you need to collect payments with your JotForm, you may add the PayPal field to the form and configure with your account. Please refer to the guide below that can help you with adding PayPal field to JotForm to create an order form.
