Well, i would recommend a "switch"

pawn Код:

switch(classid)
{
     case 0, 1, 2, 3, 4, 5, 6, 7, 8:
     {
           //What you want to do for 0-8 class ids
     }
     case 9, 10, 11, 12, 13, 14, 15, 16:
     {
          //What you want to do for the others
     }
}

You have to remeber there is a limit on the length of allowed queries in an if statement. (8 i think is the limit, you have 9 in your first if)
