That's strange. I entered your name and it seems to be working for me. What browser are you using?
In any case, you should be able to just manipulate the URL of the generated signature to get it working how you want:
*http://www.rsbandb.com/goalsigs/min-white/overall_lvl/
9999/smileyrose.png

If you generate a signature in the style that you want, just ignoring the goal level (leave it as it appears first) then you can just change the goal level in the URL like above. I'm assuming this is the kind of goal sig you're talking about, sorry if I missed something.

Very impressive stats, by the way.
