Hmm, you used the Make changes to a list of things workflow action, but you need to use the Make changes to thing action. When you use that action, you should be able to select the current page’s account as the thing to change, and then you can add the value of the venue input to the account’s list of venues.

If you can’t get it to work and you are willing to share a link to your editor, I would be happy to try to set it up for you.

Best…
Mike
