It looks like you're using SQL Server as your database platform. If so, the error message you're receiving suggests that you're trying to insert a value into an identity column. Your insert statement should not include the identity field as this value is created automatically by SQL based on your seed and increment settings for the field in question.
If you want to force an value in an identity column, you have to run
set identity_insert [GeneralNotes] on
first.
Don't forget to turn it off again if you want the identity field to be useful. To look for the identity field, run sp_help GeneralNotes.
