My problem is if the score is bigger than his personal best it adds the record to the base but at the same time keeps the previous score inside and having for example:
no you have to create a method first to check user record, and then just compare if score is > than privious then update, this block with and option will not work as good, use if not is empty username, then if score is > old score than update row ( index of username in list all username)
