[marcusami]

hey im pretty new at mysql but i have got a site going that you post info on and it is recorded in the database

but now i am trying to edit it from a webpage

i can call up the info so its displayed and ready to be edited, but I cant save the edit to the same id

when i do

mysql_query("INSERT INTO trailers
        (t_Name, t_Price, t_Loc, t_Desc, t_Loc_a, t_Loc_b, t_File) VALUES('$theName', '$thePrice', '$theTarget', '$theDesc', '$theTarget_a', '$theTarget_b', '$aFileName')  WHERE id = '$hold_Id' ") 
        or die(mysql_error());

i get a error of
