I may have been using an older version of Excel when I last tried.

I download a csv report that has two columns that I'd like to work with.
1-session start (custom format) "11/6/2008 16:59"
2-session end, same format, end of session may be in excess of 24 hours
after session start. "11/8/2008 19:32".
I would like the final column to express the total time in hours and tenths
for billing.

I have tried many suggestions but I can't make them work for me.
I can send a sample of the csv or the spreadsheet in Excel 2002 to anyone
that want's to help. I have Excel 2002. hot mail sallenss
Thanks in advance
