Hello. I'm brand new to airtable. Less than 2 days. I'm struggling a lot. I have a table with basic member info in it (member id, first name, last name, email, etc). Now, I want to create a form, let's call it "sign up for party". I want the results of this form to populate another table, but be linked to the data in the main members table.
When I create a linked field in the form, it shows EVERYONE in the table!! That's a huge security issue!! I want people to enter their member id into the form and have that id validated that it exists on form submit. When they submit, the record should be created in the new 'signups' table, linked to the main table.
how do I accomplish this? This seems fairly simple/common, yet I've spent 8hrs trying to figure it out.
