How do I link a jot form to pay pal. Me account?

How do I link a jot form to pay pal. Me account? 
Wgich widget do I select - personal, standard, etc 

And after I put in the pay pal.me account name I get error message from pay pal saying something went wrong 

what’s the trick to getting these to link up? 

Hello,

Even if you have a PayPal.me account, you would have linked it to your PayPal Standard account. Is that correct? 

When you connect to PayPal Personal or Standard - (both are same) - you will need to enter your PayPal Standard account email address to connect. No other account credential is required other than your PayPal Standard email address.
