Multiple Hover States - Not restoring to normal

Hi,

I hope someone can help?

I have 4 buttons on a master slide that change a single variable to equal 4 different colours.

I then have several objects on various slides that change colour when you hover over them, depending what the overall colour variable is set as.

So triggers on a specific slide go:

1. Change textbox1 to state red when user hovers mouse over textbox1 (restore on mouse leave), condition if variable = red 

2. Change textbox1 to state green when user hovers mouse over textbox1 (restore on mouse leave) ,  condition if variable = green 

etc. 

In this example, if the variable is red, the textboxes change red when you hover, but they then stay red forever (never return to normal state) - unexpected behaviour.  If you change the variable to green though, the textboxes change green on hover, but return to normal when you move off (as expected - yay!).

If I change the order of the triggers, whichever colour is at the bottom of the list of triggers, is the one that works (the items return to normal when you move away), but if I am on a different colour, higher in the list of triggers, the textboxes change when you hover on them, but never change back to normal.

I have no idea if the trigger order is actually affecting this, it seems to, as whichever colour I move to the bottom then works, but I'm so used to moving triggers up the list to get things to work, not down, that it seems odd.

Is there a quick fix for this?  Or have I just got too many different hovers happening at once?

Any help would be appreciated/a work around.

Thanks, Laura
