How to access total payment value of webform submission in Drupal View

Hi there,

I would like to build a Drupal View that has as one of its columns the Total Amount for the webform submission. Is this possible?

I have tried accessing the Payment field but I get a dump of the entire table, and not just the total value.

What is connecting the submission with the payment node? Is it an entity reference I can add a relationship for?

Any help would be appreciated.

Thanks,

C
