Why is Moneris option for payments greyed out?

I've been using PayPal but now boss wants to switch to Moneris.

You can only have one payment integration on a single form. It means that you need to delete the existing PayPal Standard integration in order to Moneris payment gateway. Here's a guide: How-to-integrate-Moneris-with-JotForm.

Before doing that, I recommend you back up your submissions. Please refer to guides below:

Hope that helps. If you have any questions, let us know.

Thank you! Very helpful. I thought I had deleted PayPal from my test form but had not.
