    Adding HH:MM:SS not working

    Hi,
    I have a column with hours in the following format HH:MM:SS, that looks like this:

    12:16:00
    1:35:00
    1:35:00
    12:47:00
    12:46:00
    12:51:00
    4:33:00
    4:05:00
    12:54:00
    3:19:00
    3:19:00


    I am trying to add the sum total of all hours, but its not working.
    I have my column formatted as time -> 37:30:55

    Any suggestions?
    Thanks.

    When I use the autosum function I get this:
    =SUM()

    You need =sum(<all the hours>) and to format the result cell "[hh]:mm:ss" (N.B. square brackets)

    I am not too sure I understood what you are suggesting. I added a small attachment.
    Could you show me what you mean?
    thanks.

    Your column is formatted correctly but your times are stored as text.

    Type 1 into a cell
    copy it
    select your times
    edit->paste special->multiply

    hey presto, your times become times and the world has meaning once more
