also line 73:

PHP Code:
$result .= $this->buildBranch($category_id, $level+1, $submenu, $category_link . '_'); 
to the following:

Fyi, it appears that there was a misunderstanding. The link provided to resolve this issue was to the post in that thread that resolves the issue as it is to be done in ZC 1.5.6 and makes one modification. The solution makes one modification at the start of the function rather than at each use.
