I export time statistics into Excel 2007 so that I can get totals for
multiple entries. The time format is hh:mm:ss and in the hours field it adds
a leading 0. When I set up a SUM calculation the answer is 0. If I click on
each field first which removes the leading 0 the SUM works. I have not found
a way to make this work other than to click on every cell before I add the
formula.
