ordertable categories problem

You write this syntax for using multiple categories or tags:
To show the order table at any page, use shortcode [ordertable] or [ordertable categories=”category A, category B”] or [ordertable tags=”tag A, tag B”] if you want to include only certain categories or tags.

Does not seam to work.
It works OK, when placing just [ordertable] OR [ordertable categories=”KategoriA”]
But multiple categories: [ordertable categories=”KategoriA,KategoriB”] does not work.

The same problem for tags.

Maybe you wrote wrong syntax, needs to be:
[ordertable categories=”KategoriA”,”KategoriB”] or something. I dont know.

Also – why can I not have more than one ordertable tag on the same wordpress page?
