[image] After making an ID, it’s successful to set up a nickname. However, I want to make an error if the nicknames overlap when setting the nickname. If the nicknames overlap, the account will be overwritten. I’m Korean, so I used a translator. The green circle is the ID and password, and the red circle is the nickname. I desperately need help.
