For my own curiousity...
Why mark the function volatile?

Try this small UDF:

Public Function IsFormula(r As Range) As Boolean
Application.Volatile
IsFormula = r.HasFormula
End Function


UDFs are very easy to install and use:

1. ALT-F11 brings up the VBE window
2. ALT-I
ALT-M opens a fresh module
3. paste the stuff in and close the VBE window

If you save the workbook, the UDF will be saved with it.

To use the UDF from the normal Excel window, just enter it like a normal
Excel Function

To remove the UDF:

1. bring up the VBE window as above
2. clear the code out
3. close the VBE window

Hi there,

Thank you.

That is great for locating those cells which contain a formula. However I
am hoping to create a formula such that conditional formatting will highlight
a cell if that cell no longer caontinas a formula but is instead overwriten
with a hard number by a user.

e.g. NOT(ISFORMULA(A1)) then fill cell yellow.

All,

I am aware of the IS forumlae. But how would I test if a cell is a function
that calucates a number as opposed to a hard inputted number? The end goal
being to highlight any cells where a formula is overwritten using conditonal
formatting.

The forumla in question being:

=IF(NOT(B9=""),VLOOKUP(B9,'Project Overview'!$A$34:$E$52,COLUMNS('Project
Overview'!$A$33:$E$33),FALSE),0)


Appreciated as always,

Neil
