Help with menu button re-purposing please...

[1atom12]

Greetings All,
First off, thank you Anne for the Abbington Mega template. I am trying to modify (with a horrible outcome) the "Shop by Brand" (renamed E-Liquid Options Help) selection on the top of the page. I have no need for that particular button on our site and wanted to re-purpose it to be a simple help popup for customers with questions on how to select product options. I simply don't possess the right knowledge to make it format properly. Any code help would be appreciated. I would love for it to look and behave just like the "About Us" button. Again, the button in question has been renamed to "E-Liquid Options Help". It also seems to push the entire site down about a millimeter or so when you hover over it. That's really bugging me as well...

I did some reading and copying and pasting and got it 90% there... It now leads to a dead link that I need to fix... If anyone has any suggestions there, they are most welcome...
