Hi Chris -

It looks like you have a customized _nav.html file that allows for your top nav buttons to appear on either side of your logo. You have IF statements relating to the forloop index for your top nav page array. Currently you have statements for "If forloop.index is 1" (then put it to the left of the logo) and "If forloop.index is 2 or 3" (then put it to the right of the logo). I recommend adding another IF clause to either one of those, depending on whether you want it on the left or right.  You would add this:

or forloop.index == 4

To the liquid conditional statement on line 6 or 28.
