Gscript2 Showpoly

[SSS]

I just started using gscript2 last night and figured most things out on my own,but having some probs right now with showpoly..

In the docs it says:
showpoly(float,array);
I used:
showpoly(203+imgindex,imgx,imgy,imgx+5,imgy,imgx+5 ,imgy+5,imgx,imgy+5,imgx,imgy);

I used a bunch of different variations but none worked properly, meaning the polygon wasnt shown.
Any scripter gawdz out there that can help me?
