Excel 2007 : Conditional Formatting with Icons Sets and 4 scenarios

I am having trouble applying conditional formatting using the icon set (red, yellow, and green), when I have four different scenarios that could result in those three colors. When I enter the month's ending asset number, it should display the icon based on the criterion below.

If assets are >= the Jan Budget and < the Jan High, then it should display green.
If assets are >= the Jan Low and < the Jan Budget, then it should display yellow.
If assets are < the Jan Low, then it should display red.
If assets are > the Jan High, then it should display red.

I have attached a sample spreadsheet, the formatting is working for the first three criterion listed above, but not for the fourth.
