SetPlayerSkillLevel(killerid) [DeagleSkill][killerid] + 1 );

You cant make it like this. You want your own skill info and using SetPlayerSkillLevel you are setting Server's Player Skill level. If you want like that make it:

PHP код:

public OnPlayerDeath(playerid, killerid, reason)
{
   if( reason == 24 ) // M4 weapon ID
   {
      SetPlayerSkillLevel(killerid,2,+1); 
      PlayerInfo[killerid][DeagleSkill]++;
      SendClientMessage( killerid, 0x00FF00FF, "Upgraded your Deagle skill. Keep practicing!" );
   }
   return 1;
}
