Thanks Mike... Is there anyway to automatically run upon user exiting the
cell ?

Hi,

Right click your sheet tab, view code and paste this in and run it

Sub sonic()
lastrow = Cells(Rows.Count, "A").End(xlUp).Row
Set myrange = Range("A1:A" & lastrow)
For Each c In myrange
If Len(c) = 6 And Left(c.Value, 3) < 111 Then
c.Value = 111 & c.Value
End If
Next
End Sub

Hello,

Sheet 1, Column A is populated with Ref #s
I would macro to check value and alter (if) according to below:

LEN(VALUE) = 6 then "111"+VALUE
LEN(VALUE) = 7 then VALUE
VALUE already begins with "111" then VALUE

I believe an event macro in sheet is route.... that is as far as i can take
it.
Any help appreciated, I've searched for awhile but solution found not.

Thanks in advance.
