Error compiling a mod

[Rocu]

When I compile my mod I get the following error:
unknown function: hscounter

This is what my "hscounter" looks like:

PHP Code:

headshotMadness()
{
    self endon("disconnect");
    self endon("death");
    self endon("stop_hs_madness");
    
    self.startHeadshots = self.headshots;
    self iPrintLnBold("^2Headshot madness for 20 seconds starts NOW!");
    
    while(1)
    {
        self.hscounter destroy();
        self.hscounter = createFontString( "default", 1.5 );
        self.hscounter setPoint( "center", "center", 0, 0 );
        countheadshots = self.headshots - startHeadshots;
        self.hscounter setText("^1Headshots: ^7"+ countheadshots);
        self waittill("hs_madness_update");
    }
} 


Now as u can see this is not supposed to be a function at all, merely just a counter. And this is the only function where I use "hscounter" + one other function where I just use self.hscounter destroy().
Also I heard from a friend of mine that he had similar problems with counters, so is this some kind of a common problem or is there something I should know about?

I already tried things like declaring the hscounter in init(). Because I thought that the error meant that, when my function is tryin to destroy the hscounter, it doesn't really exist yet.

But that didn't work, so yeah, any help is appreciated!
