Spreadsheet note:

 

The actual spreadsheet is here.

 

For some reason when the spreadsheet is opened, the warning box first appears that the spreadsheet contains macros (which it also tells you means there is a possibility of viruses). This is if your Excel has this macro check function turned on.

 

I did have macros in the spreadsheet that I was using earlier, but deleted them. There are none in the spreadsheet. I donít understand why this warning is still being given; perhaps it is a bug in my Excel 97. At any rate you can still open the spreadsheet, telling it to disable macros, if you get that warning.

 

Also, I use NOD32 on my computer, an excellent virus checker, so the spreadsheet should certainly be safe.
