Google spreadsheets: compare text from different tabs

There are two tabs, each one contain a list of links (column B) and a list of titles (column M). I need to check titles from column M and state if they match or not (TRUE or FALSE).

Here is the doc https://docs.google.com/spreadsheets/d/1U6Kpf7fwyiRat9XsRKyBQb8ZO_qhD8QgO4athC8zfuU/edit?usp=sharing

I am using arrayformula for this, but for some reason it failed to work.

Solution

=ArrayFormula(IF(B2:B="",,VLOOKUP(B2:B,Live!B:M,COLUMNS(Live!B:M),FALSE)=M2:M))
