Hi
I've just tried Robomaker 6.3 SR-1
First I  tried to make a simple RSS type robot, I got the error "Error from the For Each Tag action. No tags to loop through" when on click on any step after "for each tag" action.
Then I downloaded and tested the famous sample of robot : http://openkapow.com/blogs/support/archive/2006/11/24/Creating-an-RSS-robot-with-an-input-value-to-search-Digg.aspx
I got the same error message.

I wish someone tells me what is the problem.
