I keep getting an error message saying access token missing. i have it connected to my square account

I've just cloned your form and integrated it with Square, I can see the payment is going through without any problem, here's a screenshot of the record I got: 

What I would suggest you is to check that your Square account is working, you could also try to remove the integration and add it once again to your form, please make sure you've set your account to live on the connect section and test mode is set to no in the additional gateway settings. 

If the issue still persists, please  let us know. 

I checked to make sure live mode was selected and test mode set to no in additional gateway and I am still getting the token error. Do I need to click on the square connect field and log on each time I update the form?? How do I remove the square integration and then "reinstall" it?

Hi,

You don't need to connect it every time. You can delete the field on the builder:

Please try re-integrating with Square and turn back to us with the results.

Regards.
