Custom porperties & Taxonomies.

I creat a Taxonomy using query based ,but there are only predeifined porperties in the dorpdown list .

I want use custom porperty. so I creat a custom porperty

in Porperty Metadata named 'brand'.

and I crear a XML form that can give values to 'brand'

but when I Use query based builder to set a folder's query and Save the query ,It really doesn't work.

What should I do to make the Query based Taxonomy to work Using Custom porperties?

Point Awards!!
