Some weeks ago there  was a thread about how to make a spreadsheet and add your cards to a category within your store front. I tried to do the spread sheet but my Works Program wouldn;t let me down;oad it without the product number. I put the product number on the back of the cd case where it asked for it,but I kept getting a message that it was invalid. Granted ,my Works program is old,but up until now I have been able to use it. Can someone help? Thanks a lot.
