is it the spreadsheet from here: How to Brew - By John Palmer - Residual Alkalinity and Mash pH
are you opening them in microsoft excel, open office, or a similar program?
if yes, the spreadsheet is color coded. wherever you see a yellow box is where you input your data, the blue-green boxes will change automatically based on what you input. the spreadsheet is unprotected and unlocked so if you happen to change any fields other than the yellow ones you pretty much need to delete the file and download it again to be sure you're getting correct data.
