The range is selected by the:

If Target.Column < 3 Then Exit Sub
If Target.Row 20 Then Exit Sub

Delete these two rows and change it to:

If Intersect(Target, Range("C12:K20")) Is Nothing Then Exit Sub

to give:

Private Sub Worksheet_Change(ByVal Target As Excel.Range)
If Intersect(Target, Range("C12:K20")) Is Nothing Then Exit Sub
Application.EnableEvents = False
Target.Value = Target.Value * -1
Application.EnableEvents = True
End Sub

Another warning: VBA is not part of XL, it is kind of "stuck on the side of
it" so unlike formuals which will automatically adjust when you change the
environment by, say, adding a column, VBA will not. If you add a new Column
B and you now want the negatives in the Range D12:L20 the code will still
use the original range until you alter it.

What if I want different rows and colums, for instance:

C12:K20

It depends on what it is that you want to do.

So that means that whenever I entered a number in those cells, my
numbers are going to be -

If by that you mean that you are manually entering the data then surely
it
is just as simple to add the - as you type.

If you mean when you paste data into the range then you could add an
event
Macro to change the sign:

Right-click on the sheet tab and select View code and then paste the
following code into the sheet module:

Private Sub Worksheet_Change(ByVal Target As Excel.Range)
If Target.Column < 3 Then Exit Sub
If Target.Row 20 Then Exit Sub
Application.EnableEvents = False
Target.Value = Target.Value * -1
Application.EnableEvents = True
End Sub

This will change all positive values typed of pasted into C1:C20 into
positive values and all Negative values into positive ones

One note of warning, formatting will make a number LOOK like a
negative
number but the value held in the cell will still be positive.

Try entering 123, (it will show as -123 of course), in C1 then -1 in
a
cell
that has not been formatted - say D1. Now enter in D2 enter =C1*D1
you
will get -123 whereas if C1 had really been negative you would have
had
123
returned.

You can try this:

Select C1:C20
Format Cells
Number

-#,###,###.00

This should do it.


I would like to cells's C01:C20 do negatives numbers.
