Getting tired?

 ... textbox  ...  rowsource ...

or did I miss a new feature?

Kelvan,

Thank you for replying, but I don't quite understand your solution.  I have
a table tGeneralInfo with a number field "TotalRepairHours" where number of
hours required to complete job should be entered.  I have another table
tWorkLog with date/time fields StartTime and StopTime which are on a form
fTimeSheet with DateDiff calculation to give time worked for each record.  I
also have a field "SummedHoursMinutes" which gives total time worked for each
job.  The form fTimeSheet is a subform on the form fGeneralInfo and is
related by job number.  

This being said all calculates and links together as it should.  I think the
problem is how to subtract "SummedHoursMinutes" which is a date/time field
from "TotalRepairHours" which is a number field.  

If you can further explain how I can use your solution or have any other
ideas, I would appreciate it.
Thanks again,
Phisaw

I have solved the problem. Thanks for your time.
