VB String Written Cross Refers Tab2 On A Spreadsheet

I had the following VB string written for me recently, that cross refers Tab2 on a spreadsheet to tab1 with any duplicated fields in Tab1 being moved to Tab3.

Column B is the column I am comparing over the 2 sheets...



Sub DIVIDEND()

Dim Master As Worksheet 'Tab 1
Dim RefTab As Worksheet 'Tab 2
Dim NewTab As Worksheet 'Tab 3
Dim Cell As Range
Dim iRow As Long
Dim jRow As Long
Dim ff As String

The addition I would like to add is after this first action has taken place, I need all all of the data that is in Tab2 and not Tab1 moved to Tab 3.

To summarise, I need any info that appears in Tabs1 & 2 moved to Tab 3 and any remaining lines that are on Tab 2 and NOT Tab1 moved from Tab2 to Tab3.
