Thanks Andy, but it's still not working properly.

If the static URL of the category page is:

/cat1/cat2/more3.html

When I use:
<%make_category_url($Full_Name)%>

The result is:
/cat1/cat2/index.html (more3.html is not included)

I have also tried the <%page_on%> tag:
<%make_category_url($Full_Name)%><%endif%>/more<%page_on%>

And the result is:
/cat1/cat2/index.html/more3.html

Only need to delete index.html

Cheers,

JoseML
