pawn Код:

if(IsPlayerConnected(giveplayerid))
{
    if(giveplayerid != INVALID_PLAYER_ID)

Pointless checking. If the players are connected, then they simply not invalid players.

pawn Код:

SetTimerEx("SearchCallHome", 2000,false,"i",playerid);

Of course, it won't. You pass only playerid as parameter when it should be:

pawn Код:

SetTimerEx("SearchCallHome", 2000,false,"ii",playerid, giveplayerid);

But still.. wouldn't it be better without the timer? Just calling a function and do the rest?
