Use a form to update an existing record in Airtable

Hello to the whole community!
I had a question when generating the link. In the example you use Guest ID and Guest Name, but in my case I want to use the variables Project and Accounts, which are multi select. When I create the link I see all the options that are in these variables, but in the form I only see the first of them.
Here you have some pictures of what I’m talking about:

  • Fields:
    image

  • Link:
    image

  • Formula:
    image

  • Form
    image

Any idea how I can fix this?
Thank you very much in advance!
