Hi Brian,
I woant a formula which when referring to another cell
verifies whether this cell contains a numerical value or
otherwise a normal numerical number
Click to expand...

=IF(ISNUMBER(A1),"A1 contains a number","A1 Does not contain a number")

Hi Brian!

I'm not sure whether I'm interpreting you correctly.

If a number is entered as text (eg by preceeding with an apostrophe) then

=ISNUMBER(A1)
will return FALSE

But:
=ISNUMBER(--A1)
will return TRUE

However, if A1 is an empty cell, then ISNUMBER(--A1) will return TRUE which
may not be what you want.

So for testing, you might use something like:

=IF(ISNUMBER(A1),"A number",IF(ISBLANK(A1),"Blank",IF(ISNUMBER(--A1),"Text
Number","Text")))

Hi Brian!

If you are wanting to test whether a cell contains a formula you can use the
User Defined Function:

Function ISFORMULA(MyCell As Range) As Boolean
ISFORMULA = MyCell.HasFormula
End Function

But what i mean is ...

if in a particular cell, there is a valid number but which
is a result of another formula, I want it to return false
and not true... I want tru to show ONLY for manually input
variables and not for formulas returning a number..

Hope I made myself clear

Thanks again,
Brian

Since you're new to macros, you may want to read David McRitchie's intro at:
http://www.mvps.org/dmcritchie/excel/getstarted.htm

Short course:
Open your workbook
Hit alt-f11 to get to the VBE (where macros/UDF's live)
hit ctrl-R to view the project explorer
Find your workbook.
should look like: VBAProject (yourfilename.xls)

right click on the project name
Insert, then Module
You should see the code window pop up on the right hand side

Paste the code in there.

Now go back to excel and test it out.
