Hello friends, I have this problem every time I try to add more than one record, the first one saves it to me, but when I create the second, the next error occurs, I hope they help me, thanks ERROR: Error in inclusion - Registration already exists
What I expect is that you have setup a key for the table, but that it’s value is not changed on each record. A database needs a primary key to function and that primary key needs to be unique for every record,.
it would be your settings are wrong, just in case, please attach an screenshot.
