Why does this not work?

My Void:
[PHP]void autofire(void) {
keybd_event(VK_LBUTTON,0,0,0);
}[/PHP]

And my Command:
[PHP]if(GetAsyncKeyState(VK_NUMPAD1)<0) { // v
autofire();
}[/PHP]

I want to make it when I press NUMPAD1 it will press the left mouse button. The first time I tried it totally messed up. And shot until I reloaded. And now it wont work at all? I don't know what happened? Can someone please help? I'm so

first of all are u trying to make rapid fire?
and ur sig is trolling

if you can make OPK TELEKILL and a REAL GLITCHER i'm sure u can code some basic commands by yourself
