Thought I would post this code for posterity. I developed it with help from
this group.

I use this module in conjuction with a simple user interface. It allows the
user to develop a list of formulas to "freeze". When I say freeze, I mean paste
the value of the formula to the cell. This is helpful for people who need to
email formula-laden worksheets to others who do not have the requisite excel
modules to use the formulas (in this case - Hyperion Retrieve). Email me to
get the complete add-in with UI. Below is the guts of this addin.

This code has been tested to a limited extent. However, the error trapping
is not yet fully developed. As errors arise, I'll add to it.

Public Function RecordAdd(strNewFormula As String) As Boolean
'This procedure expands range name for formula list and adds new record.
'The Range name is FormulaList and it must exist, or an error will occur.

RecordAdd = False

.ScreenUpdating = False
End With

'Test to see if forumla already exists in list. If it does, exit.
With Application.Workbooks("Formula Freeze.xla").Sheets("List").Range("FormulaList")
Set rngTest = .Find(strNewFormula)
If Not rngTest Is Nothing Then
Exit Function
End If
End With

'Add new formula to list.

lngRows = .Rows.Count + 1
.Cells(lngRows) = Trim(strNewFormula)
