Because I use VBA for just about everything, my approach is a bit more involved...
What I would suggest is to create a Worksheet_Change event: Option Explicit Private Sub Worksheet_Change(ByVal Target As Range) Dim I, Col_Name, Col_Pin Col_Name = 1 'Column to monitor for content Col_Pin = 2 'Column to show PIN For I = 1 To Target.Count '(necessary for adding multiple lines) If (Target(I).Column = Col_Name) And (Target(I).Value <> "") Then 'Check to see if a change is made to a monitored column 'and it is not empty If (Cells(Target(I).Row, Col_Pin) = "") Then ' Is PIN cell blank? 'changes cause the event to run itself, so turn off Application.EnableEvents = False Cells(Target(I).Row, Col_Pin) = _ Application.WorksheetFunction.RandBetween(1000, 9999) Application.EnableEvents = True End If End If Next I End Sub Do you know how to add it to the sheet macro module? let me know...

The purpose is to assist in generatating unique PIN numbers for users on our phone system.. The numbers generated need to be a number between 1000 & 9999... The basic formula I have used (=RANDBETWEEN(1000,9999)) does it initially, but if the formula gets extended or a row gets deleted the numbers are regenerated.... The numbers need to remain how they are at the initial time of running the formula.. Any ideas? – I guess there needs to be some fault tolerances involved, but for the life of me I would know what they are....
