My data table looks like this:

Date AA BAC DELL
20071203 4.83% 19.72% 7.50%
20071204 6.27% 10.49% 10.02%
20071205 10.61% 2.12% 5.32%
20071206 5.31% 20.33% 12.82%
20071207 8.64% 7.70% 2.97%

I am looking for a formula for ColC of this table:

Date Name Percent
20071203 AA 4.83%
20071203 BAC 19.72%
20071203 DELL 7.50%
20071204 AA 6.27%
20071204 BAC 10.49%
20071204 DELL 10.02%


Thank you in advance.
