I am new to Retool and have been trying to set up a simple CRM for my org and cannot define a variable. The context is an airtable base using the Baseql integration to link to Retool. I have been following the documentation for that application and graphql in general.
I am trying to filter my query based on a dropdown naming that variable "$customer" but Retool has the variable definition UI grayed out. See image. Let me know where I am making a mistake.
