Try this:

pawn Код:

COMMAND:command(playerid, params[])
{
      if(sscanf(params, "s[20]I(-1)", name, slot)) return // blablablalalala
      if(strcmp(name,"putin",true) == 0)
      {
              if(slot == -1) 
                    return YourStuffHere //slot is '-1' , which means it isn't changed from the default value, which again means that player didn't put anything in the second param
              /* Do your stuff */
       }
       else // if 'putin' isn't the first param put
}
