What you are describing is exactly that
Depends upon the # of options selected
Thanks for your contribution Kobra. I am trying to explore utilising a native function in Zen Cart to perform this basic type dependency. I was hoping my angle would get the creative juices flowing beyond "Zen Cart doesn't support that!" which is the frequently featured punch line to any post with "attributes" in the title

I've seen dependent attributes being hacked together with javascript headers and DIV wrappers, but do you think this could be a cleaner alternative in this case?
