Duplicate entry ‘127′ for key 1

Well I’m not so familar with SQL, that’s why I was struggling with that problems for about 10 minutes. Actually it’s fairly simply, the error message says that there is already an entry with the ID 127 in the database.
The problem is the size of the SQL field. A signed TinyINT can only save entries from -127 to 127, an unsigned TinyINT can hold entries that range from 0 to +255.
You can find some more information about it here.
