Aha gotcha! Many thanks. Thats working great and was something that I needed to be able to get some breadcrumbs working on the product detail page.
On that page, however, regardless of which section the product is in, the first record of the table (shampoos) displays as the section rather than the right one and as a result the link back to the category sections is also set to 'shampoos'.
If you look at http://www.hairmekanix.co.uk/product/hairdryer , the breadcrumb should be 'Electricals' rather than shampoo.
Have attached the page.
In the ProductsCategory recordset I have toggle the $colname_ProductsCategory = between 1 and -1. With -1 it doesnt show the category at all (its just blank between >> >> ) and with 1 it shows the category albeit incorrectly.
