Excel graph showing wrong data

I have plotted several months (Nov06-Oct07) of data and graphed it out. On my pc and several others, it opens correctly, but on several others, the dates start at 10/0/1900 and continue as 12/31/1903,12/31/1907, and so on. All the other dates start with 12/31 with different years. So instead of 1 year of data broken down monthly, I have 103 years of data broken down with 4 or 5 years  between. All pcs are running either office xp or 2003 with some of each working correctly and incorrectly. It appears that somehow the cells are being defaulted as time data instead of currency on a few pcs thus showing dates instead of currency ranges, and I don't know why.

Do all PCs have the same regional settings in Control Panel?
Can you post a copy of the workbook (censored if necessary) at www.ee-stuff.com?

Everyone is in the same region, and the same office. They wouldn't know how to do anything except open the file, so they couldn't have changed any local settings by themselves. I have posted the file.

Ah, you are using the EOMonth function, which requires the Analysis toolpak add-in to be loaded. You will either need to make sure that all your users have it loaded or adjust the date functions in row 3 to read (for D3):
=DATE(YEAR(C3),MONTH(C3)+2,0)
and copy it across to N3.
