I originally posted this in another area and no one came up with a solution so I am trying in this thread.

I have two stores, both using version 1.3.9d. I use EP 1.2.5.4 to populate and update prices, inventory, etc.

I download an inventory update daily from my supplier. I set up three columns in my spreadsheet, v_products_model, v_products_quantity, EOREOR, and upload those three columns to my sites.

For some reason my prices(v_products_price) are also being changed without having a column for them in the upload. Both stores doing the same thing.

The prices are increasing by 7% each time I update quantities. I think it may be related to the 7% tax rate(FL) I have set. I just recently changed the status on all items to "taxable goods".
I think this started when I changed status. I don't recall any problems prior to the change.

Why is this happening and what can I do?

I've gotten around the problem by uploading a file with just the correct prices after I update the inventory, but I should not have to do that.

thanks
