Re: Still error messages!!

I made that.. but there is something strange!! I SELECTED field from the database.. but it is not showing what it contains!! This is what is shown on the screen : UPDATE accounts SET LogoutTime=1075313199SELECT LoginTime,Distance,LessonNumber FROM accounts WHERE UserName='' AND Password=''UPDATE accounts SET LessonNumber=LessonNumber + 1 Query error: You have an error in your SQL syntax near '0') WHERE UserName= AND Password=)' at line 1 So what is wrong!!!?? Everything is inserted and updated correctly in the database.. but the distance is the same.. no changes.. no updates!!
