Excel - how to record a function's result despite future changes?

[starflight33]

How can I automatically record a single moment's result for a function to
preserve it, when future changes in variables accessed by the function will
change it in the future?

Change it to a value

To clarify: I'm looking for my formula to update its calculation everytime
the variables it depends on are updated, ~and to record each calculation
separately~. At this point I'm manually typing the result in a cell, but am
hoping to be able to have Excel do this, without my typing or preferably
without even having to use a macro.

Is there a solution?

If desired, send your workbook to my address below along with a snippet of
this message copied to an inserted worksheet and clear examples of what you
want. I will take a look tomorrow before the Texas game.

Copy down
=IF(LEN(TRIM(C2))<1,"",SUM($D$22)/SUM($C$2:C2))
or
Private Sub Worksheet_Change(ByVal Target As Range)
If Intersect(Target, Range("c2:c4")) Is Nothing Then Exit Sub
If Len(Application.Trim(Target)) < 1 Then
Target.Offset(, 2) = ""
Else
Target.Offset(, 2) = Range("d7") / Range("c5")
End If
End Sub
