Avoiding Duplicate Entries

[ThinhDinh]

Then I would advise you to create a custom form.

How do I create a custom form?

I’m just dropping this here so I have something to refer people to when they ask. This is a simple concept app (copyable), that demonstrates the following techniques: Building custom forms for adding and editing list items (as an alternative to the native forms provided by Glide) Preventing duplicate new entries using User Specific Columns and Relations Enforcing mandatory input items The use of visibility conditions and user specific booleans to control user flow There is nothing particula…

With those 3 fields, you would create 3 relations that match with the existing phone, email and company name columns in your database.

If there are any relations that is not empty, you don’t allow them adding a row to that Sheet.
