Select Case code not executing macro on Dropdown (change)

Please see workbook. The module 'Navigation' has macros that simply go to a sheet when the drop down is changed to a certain word. The first subroutine is for the drop down on the 'Navigation' worksheet. I am trying to call the navigation macros when the drop down changes.

I think I have the code right... But maybe it's not in the right place or something? Can someone take a look and help out?

Thanks!
