Hi ,  
After a standard form submission , I trigger an customize action which contains a test.  
If the test is true , I want to avoid to add a row.  
The notif comfirms that the test is valid but although I use a “Go back” action, the row is added.  
How can I do to avoid this ?

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](https://docs.glideapps.com/all/reference/data-editor/user-specific-columns) and [Relations](https://docs.glideapps.com/all/reference/data-editor/computed-columns/relation-column) Enforcing mandatory input items The use of visibility conditions and user specific booleans to control user flow There is nothing particula…
