This means that when the value is inserted, it will try to cast an varchar (the value you wrapped in single quotes) as a numeric value, and fail. You need to identify which of the values you are trying to insert is numeric, and remove the single quotes from it within the insert statement. For example: string.Format("INSERT INTO Kabala1 (Nu_kabala,Ma_num,Date,Time,Total,Status,Name,User_n) VALUES('{0}','{1}','{2}','{3}',{4},'{5}','{6}','{7}')", n, Session["Ma_num"], now, tm, lprice, "sdfsdf", Session["user"], "sdfsdf"); Where {4} is numeric. share|improve this answer answered May 18 '14 at 17:29 Daniel Hall 362 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post

If i leave some of the fields null i get the error. If it was about wrong conversion i would get the error message in all insertions not only the ones with null values, right?
