Trying to add Facebook tab

Trying to do facebook tab, I selected embed, copied code from the publish section but instructions say to enter my code where it says var iframe =. This piece of code does not exist from the code i copied..

Any help?

The arrow is actually not specifically for the var iframe =, but instead, you need to paste the iFrame Embed code that you just copied into the whole section.
