Pearson matrix correlation calculation in Excel

[jatkinson]

I am trying to use correlation to calculate r values for the following data, but calculated values are "Div/0." Can anyone correct my improper setup?

55	19	40	13	222	12	74	540
19	40	13	222	12	74	540	55
40	13	222	12	74	540	55	19
13	222	12	74	540	55	19	40
222	12	74	540	55	19	40	13
12	74	540	55	19	40	13	222
74	540	55	19	40	13	222	12
540	55	19	40	13	222	12	74

Thanks,

Jon
