Totaling times

[Guest]

I have a form where the keyboardist types in the start time and end time for
a person and operation. That in turn totals the run time for that person and
operation. That all workes well. When I try to total the entire job time it
"resets" after 24 hours (if a job totals 25 hours only one hour will show on
the total). How do I get all the hours to total. This has no date reference.
Thanks

You really need a date reference to be able to do that.
