Hi!

Honestly its nothing to do with your version. I never had issues with addons because of version.

Truth is I just realised I might have similar problem to yours.

You say you dont use any attributes so I'm assuming you would use the filter to say filter a price range within a general category.

This works fine for me for sub-categories but not for the top categories.

So I can filter products based on say Rings->Cubic Zirconia
for example for a price range 10 - 20

but not just Rings.

I realise the reason for this is because the Rings top category doesnt actually and directly contain any items it only contains subcategories.

But this really sucks as its confusing since someone might want to see ALL rings in size 8 and not just rings in a specific subcategory.

This seems to be a general problem with the way Zen Cart works and the way this add on was designed.

Is anyone feeling me here?
