Paypal Field: How to fetch data from a field?

I am trying to add a PayPal payment option on the event registration form I am building.

I would like to pass the name of the person registering through to PayPal. This helps us reconcile payments. I see an option to 'Fetch data from a field' but it only has a small subset of fields from my form. I don't see the 'Name' field to select. 

Why can't I see all my fields?

Thanks,
Carol

You can follow any of the workaround here:

1. Add a Short text entry field in your Form to get the input of your user's name.

2. Add a Form calculation widget and get the name field here. Then pass this variable to the PayPal field.

Note: Only Short text entry field and Form calculation widget are supported in the PayPal field.

Let us know if you have further questions.

Thanks.
