I'm currently trying to get my URL's to be like the following:

category/brand/offer/

• Category has a title
• Brand has a 'shortName' property.
• Offer has a title

My plan is to have it so that it goes something like fashion/asos/50-off

{parent.uri}/offers/{slug}

I've tried quite a few variations but can't seem to get it right, still loads a 404 page or throws an error in the dashboard when trying to save entries again.

Any help would be brilliant!

EDIT

• Offer entries are related via the relatedBrand entry field.
• Offer has not category related to it.
• Brands have a category field.
