here is count down i've made long time ago... maybe you can use this...

pawn Код:

new count1,rCD=0;
forward CountDown(playerid,Time);
CMD:cd(playerid,params[])
{
    new tt;
    if(sscanf(params,"i",tt)) return SendClientMessage(playerid,COLOR_WHITE,"How To Use: /Cd [ Time ]");
    if(rCD==0) 
    {
        rCD=1;
        return SetTimerEx("CountDown", 1000, false, "ii", playerid, tt);
    }
    rCD=0;
    return SendClientMessage(playerid,COLOR_WHITE,"CountDown Running Wait 'till its done");
}
public CountDown(playerid,Time)
{
    if(Time==0) //under this if you can put what ever you want to happend
    {
        KillTimer(count1);
        return SendClientMessage(playerid,COLOR_WHITE,"The Time Has Passed");
    }
    new str[128];
    format(str,sizeof(str),"~b~%d Seconds Has Left.",Time);
    GameTextForAll(str,1000,3);
    return count1=SetTimerEx("CountDown", 1000, false, "ii", playerid, Time-1);
}
