Adding a LinkPoint through script

Hi,

I 've tried to use the addLinkPoint(..) function but it doesnt work. I got crazy numbers on my Link point.

I'm using it like:

%this.addLinkPoint("100.597992 -42.447083");

What i got was this numbers:

-9189.532227 -10341.974609

Any help would be really apreciated.

Thanks
