ActiveSelect just stopped working!

Hi,

I had been going crazy trying to figure out how to do a certain thing (you can see details here http://drupal.org/node/74747 and here http://drupal.org/node/74651) and I discovered I could do almost what I wanted to do with activeselect and the category module (Ideally what I wanted was: depending on the category chosen in the first dropdown, a different number of dropdowns would be available, with different labels as well). In the end I went for a solution involving 4 fixed dropdowns Select Medium, Options1, Options2, Options3. Four Containers, with 3 of them set to distant parents pointing to the first one.

So I followed all the instructions I found, setup my 'Select Medium' container, setup my Options1 container. ANd it was working brilliantly!! The options1 dropdown was filtering to what the 'Select Medium' was set to.
I then setup my Options2 and Options3 containers, again distant parenting 'Select Medium', and they all stopped working! Whenever I select something from my Select Medium dropdown, all other dropdowns go empty! I tried to go back to the config I had when it was working, disabled the other 2 containers and kept only Select Medium and Options1... and it still doesnt work! I list the categories of Options1 and they are all in the correct container (Options1) and have the correct parents (the relevant parents in Select Medium) - but the dropdowns are empty now! I have no idea what broke it, as i didnt even touch the options1 categories befpre it broke... it seemed to be when I added more containers with the same distant parent container

any ideas what this could be? or what I should do?

P.S. all of my categories are transformed flexinodes, dunno if that has any effect....
