for cell B2:
Under Conditional format, change first box to "formula is", input:
=COUNTIF(A:A,B2)0

Replace the A:A callout with name of range, if desired. Copy formatting to
other cells. (alternative, select all the cells you want to format, with B2
being the active cell, and then apply this formatting).

Hi and thanks in advance.
I have 2 columns of Data, A & B. Column A is a Named Range. I would like
to lookup and format cells in cloumn B if the value in a cell exists in the
column A named range. I believe I need to used the vlookup formula in
conditional formatting but am unsure and do not know how/where to create the
formula.

Again - Thanks
