Or using text formfields, with the document protected for forms, and an 'on exit' macro to do the calculation and insert the result
into the required cell (eg via another formfield). A suitable 'on exit' macro might look like:
Sub TimeDiff()
With ActiveDocument
.FormFields("Text3").Result = _
Format(CDate(.FormFields("Text1").Result) - CDate(.FormFields("Text2").Result), "HH:mm")
End With
End Sub

The easiest thing would be to insert an Excel spreadsheet into the Word document.

Hello. Is there a relatively easy way to have a formula in one cell show the
product of subracting the time in cell B minus cell A? I know how to do this
in Excel but would appreciate guidance about doing this in Word 2007.
Thanks!
