Author's Spreadsheets?

To anyone who knows spreadsheets,

I was wondering if someone can help me....

When it comes to spreadsheets, I'm lost, but it seems that a simple spreadsheet would be great to keep track of my published book sales. Something I can add daily/weekly counts that can let me track how the different books are doing, and to keep tract of those who I a sharing royalties with.

Any takers?

Thanks in Advance!
