Hi cyberndj,
Sorry I am late with my reply.
It looks as though you have added child attributes fine for that product and now it isnt working, is that right?
I can't honestly see why that would be the case, maybe a conflict with another addon??
You could try adding this in /admin/child_attributes.php:
echo $oa_action;
above this:
switch ($oa_action)
This will output the action to the screen and you should see like the image attached. By doing this you can at least see if the actions are being called properly, by the look of your image the dropdown boxes arent even showing, they should be there but empty if no options were found for the product.
