I am a newb to all this so I am hoping you can help. I have searched the forum but to no avail. I have populated my Zencart setup using Easy Populate. However I have now come to set up a Sale and have found that all my Master Category ID fields for all of my products have been set to zero and hence I am unable to set up a sale.

How do I go about fixing this problem? The EP upload format does not contain a field for setting the master category ID (or does it?).

Thanks

Gary
