On slide entry conditional action that jumps to another slide?

I assumed this would work, but it's not - should this work and I've got an error somewhere or do I needd another approach?

So I have a menu slide with 6 buttons, each button simply jumps to a specific slide.  On each of those slides is a return button with an action that increments a variable (varCount) and jumps back to the menu slide.  I would like to set it up where once the user has hit all the slides (varCount=6) and hits return, the menu is bypassed and they are jumped to a closing slide instead.  To do this I tried to create a conditional action that compares the variable (if var = X then goto slide Y) and the have that action run on entry on the menu slide.  However this doesn't appear to work.  Should it?  I know as an alternative I could modify and put the conditional on each return button instead, but before I do I want to see if I'm missing something on the current aproach
