pawn Код:

if((Level[playerid] >= 0) && (Level[playerid] < 10)) {
    //stuff from 0 to 9
}
else if((Level[playerid] >= 10) && (Level[playerid] < 45)) {
   //stuff from 10 to 44
}
else if((Level[playerid] >= 45) && (Level[playerid] < 70)) {
  //stuff from 45 to 69
}
else if(Level[playerid] > 69) {
   // from 70 and higher
}

Or you could so a switch:

pawn Код:

switch(Level[playerid])
{
    case 0 .. 9:  { Dialog } 
    case 10 .. 44: { Dialog }
    case 45 .. 70: { Dialog }
}
