Adding a link to node in extra voting forms?

I want to make it so that when you click the scorebg image it takes you to the scoop page (like when you click the digg button). I found where I need to add the link to the extra voting forms module but I have no idea how to call the link of the current node/scoop. Any ideas?

Starting around line 1382 in extra voting forms module:

$form .= '

sk_id.'">

'.$negative_karma_str.'
'.$karma_score_display.'

0?'_clicked':'_not_clicked').$clickable_string.'" for="u'.$o->sk_id.'">
sk_id.'" type="radio" name="karma_vote" value="'.$up_type_str.'"'.($default>0?' checked="checked"':'').'/>
Up

I have tried urlencode($url), $url, <?php print $node_url ?>, <?php print drigg_link($node) ?>, and everything else I could think of but nothing works. I am not a programmer at all and I can't seem to figure it out. Any suggestions or help would be greatly appreciated.

Thanks -

John
