This comes from after I resolved another issue,..

I got Openoffice Calc I'm working with. I opened the zen_products_attributes in the database to change prices more efficiently. My question is,.. if I add a code in a column, like to the far right to change prices by percentage in the existing price columns, would that damage that file in the cart by that new input simply being there? My hopes is that it won't even be recognized, but the prices that where changed by that column would still be altered and implemented. does that make since?
