Thanks Clarry! I ended up googling it and found an easy 5 step process, which was spot on (I use Openoffice as opposed to Micro$oft Excel). Really the only difference between the 2 was how to add up the totals. I think in MS you input a code, whereas in OO you just hit a button. I couldn't believe how easy it was once I knew how. It always looked so complicated!
Now I get to spend the next month inputting all the details from sales I have scrawled on little bits of paper!
