Try changing your whole code with this:

PHP код:

public OnPlayerTakeDamage(playerid, issuerid, Float: amount, weaponid, bodypart)
{
    if(issuerid != INVALID_PLAYER_ID)
    {  
         if(weaponid == 34 || weaponid == 23)
         {  
            if(bodypart == 9) 
              { 
                  if(gTeam[playerid] == gTeam[issuerid]) 
                  { 
                      SetPlayerHealth(playerid, 0); 
                      SendClientMessage(playerid, -1, "You can't headshot your teammates"); 
                  } 
                  else 
                 { 
                      SetPlayerHealth(playerid, 0);  
                  }
              }
          }
    }                  
    return 1;
}
