The "sort by random" does not work when it is used with ubercart "add to cart" or "buy now" link.
but if sort by anything else, etc title, date, etc, the submit buttom "add to cart" work without any problem.

Clicking on the add to cart just point back to the same page.
I scanned the html, it looks like view does not returm the proper value (the

)

Can see the problem at
