I am having trouble with categories and sub-categories, with the sub-categories not showing up if the main category does not have any links in it.

Links

Links/Swimming_Pools

Links/Swimming_Pools/Canada

Links/Swimming_Pools/United_States

Links/Swimming_Pools/Great_Britain

On the Links page it correctly show the subcategory of Swimming pools http://www.gardenbuildings.com/directory/Links/

On the Links/Swimming_Pools http://www.gardenbuildings.com/...inks/Swimming_Pools/it does not show the sub - sub-categories of Canada, United_States, Great_Britain etc unless I put at least one link just in Links/Swimming_Pools which, ideally, I do not want to do. I want this page just to be an index to the sub-categories of Canada etc.

Can anyone help?
