In a list I record the time spent for a specific activity daily. At the end
of the month I would like to add up these the records to a monthly total. The
record is very simple: In cells A1- A 31 I write on the format HH:MM. What's
summing up formula for this?

Hi

=Sum(A1:A31)

The cell has to be formatted as custum : [tt]:mm, to show the result in
hours.

Hi

If the sum range holds any time value, the formula cell should show the time
total.

If I add two values in the list for example A1+A2 it shows the correct
result. The formula "SUM" does not seem to fix this

The list has been exported from Access 2003 to Excel. Can this be part of the
problem? If I write new time values in an Excel sheet the SUM-formula works

You've probably got text instead of real times.

Thanks a lot
