Could you please provide more detail?
For starters, from where/what download link was the software obtained?
What version of Zen Cart?

Once installed, what are the settings for: configuration->Dynamic Dropdowns?
What are the settings for: configuration->Stock in particular those towards the end of the list.
what has been done to populate a product or does this issue occur without trying to do anything to populate it?
