I am trying to create a view that uses args to show nodes that have the terms from different vocabularies passed through the URL.

I have several vocabulary/terms similar to this:
COLORS (vocabulary)
red (term)
green
blue
SHAPES
circle
square
so on and etc...

I would like to go to
http://www.example.com/something_here/red,circle OR
http://www.example.com/something_here/circle,red
(or something similar in case I have my syntax incorrect) and it would list all the nodes that are tagged with red AND circle.

Any help would be greatly appreciated!

thanks,

david
