Help with this Script Please

[Yami]

I found this antibot script on an archived post. The 30 second timer for the script is not working. Can someone help me with this please?

 

Here's the script, I edited some part of it to suit my wanting. It's just that, the timer is not working.

-	script	AntiBot2	-1,{
//OnPCLoginEvent:
//	setoption 0x40, 0; // prevent abuse
//	end;
OnCheat:
	dispbottom "too long";
	atcommand "@kick "+strcharinfo(0);
	//sc_end sc_berserk;
	//percentheal 100,100;
	//setoption 0x3, 0;
	end;
OnNPCKillEvent:
	if ( rand(500) ) end; // 1% chance to triggering
	setoption 0x3, 1;
	sc_start sc_berserk, 1000000000, 1;
	addtimer 30000, strnpcinfo(0)+"::OnCheat";
	set .@respond, gettimetick(2);
	mes "if A = "+( .@a = rand(1,50) )+", B = "+( .@b = rand(1,50) );
	setarray .@arithmetic$, "+";
	mes "How many is A "+ .@arithmetic$[ .@arithmetic = rand(1) ] +" B ?";
	switch ( .@arithmetic ) {
	default: .@answer = .@a + .@b; break;
	case 1: .@answer = .@a - .@b; break;
	case 2: .@answer = .@a * .@b; break;
	case 3: .@answer = .@a / .@b;
	}
	next;
	input .@input, -100, 100;
	deltimer strnpcinfo(0)+"::OnCheat";
	sc_end sc_berserk;
	percentheal 100,100;
	setoption 0x3, 0;
	if ( gettimetick(2) > .@respond +30 ) {
		mes "you taken too long to answer";
		atcommand "@kick "+strcharinfo(0);
		close;
	}
	else if ( .@input == .@answer ) {
		mes "Good Job";
		close;
	}
	else {
		mes "Wrong";
		atcommand "@kick "+strcharinfo(0);
		close;
	}
}
