Vb Source Code to Located duplicates from another workbook and highlight

[Sammy1994]

Hello,

I'm currently working on a database/master-log work book and I am needing to add a VB code or such to allow my workbook with the repairs to look at the master data workbook (which contains many tabs)
To highlight the duplicated values in column B in the repair workbook, While it looks for duplicates in the master-log in Column A. I'm a newbie it VB so writing a code isn't any where near my skill level. Also the reason I have 2 workbooks instead of combining the two is I'm trying to avoid allowing any scripts to run on the master-log.

Thank you,

Sam
