Hi,

I have the following data:

Logins Trimmed agent
933,858 Mozilla/4.0(compatibleMSIE6.0WindowsNT5.1)
66,788 Mozilla/4.0(compatibleMSIE6.0WindowsNT5.0)
55,989 Mozilla/5.0(WindowsUWindowsNT5.1en-USrv:1.8.0.6)Gecko/20060728Firefox/1.5.0.6
52,918 Mozilla/4.0(compatibleMSIE6.0AOL9.0WindowsNT5.1)
50,868 Mozilla/4.0(compatibleMSIE6.0WindowsNT5.1InfoPath.1)
43,339 Mozilla/4.0(compatibleMSIE6.0WindowsNT5.1Maxthon)

I can get a count of all unique agent strings using, say, IE6 by using
COUNTIF(B:B,"*MSIE6.0*"). However, I'd like to get total of all logins
by IE6 browsers. That is, I'd like a sum of all values in column A,
where the corresponding cell in column B contains "*MSIE6.0^"

Is this possible without reverting to VBA?

Thanks

Tim
