I am using Umbraco URL rewriting to make some pretty SEO URLs for a website.

OldURL : http://mydomain.com/photogallery.aspx?album=TestAlbum&picture=12

NewURL : http://mydomain.com/photogallery/TestAlbum/12

And it works. Problem is my Macro controlling the page depends on the querystring values.

<umbraco:Macro album="[@album]" picture="[@picture]" test="Hello World" Alias="GalleryController" runat="server"></umbraco:Macro>

  <xsl:value-of select="/macro/test"/>:
  <xsl:value-of select="/macro/album"/>:
  <xsl:value-of select="/macro/picture"/>

the OldURL works, returning "Hello World: TestAlbum : 12"

The NewURL returns "Hello World : : "

Any tips/ideas how to force this to work? I am loving the NiceURLs and UrlRewriting; but these little (often simple) hangups are driving me insane.
