Add menu-2 to the project
.show() will display the <a> tag as inline, but I want it to display as a block.  So I set the 'display' property manually with .css(), which is what .show() is essentially doing (albeit to the wrong value)
Pretty format javascript -- i used a sublime plugin called "format javascript".  It just adjusts tabs/spacing
I prefer outlining my variables like this in js
Remove commented code?  it's in source control if you need it later
I prefer 4 spaced tabs.  It's a preference thing, just cleaner to me
Whitespace
Variable declarations
Missing semicolon
Var cleanup, don't declare var dispphone twice.  declare it once as null and then assign it the appropriate value.
You want to use === for comparisons in js.  It's basically ==, but it forces the types to be the same as well as the values.  Js is weird in this way, and u can read more on it if you want to, but in general use === moving forward.  Also !== instead of !=
