    I have setup a couple of payment forms, put in the API and transaction key info (and double checked that it was correct.

    When I test integration i get the following error message:

    "Error 33: Phone is required."

    I have looked through documentation and the support area, but could not find any information about this error and how to fix it.

    Thank you.
