Color Formatting

Hi All,

I am trying to format a % measure called "Learning Percentage Completed" with red when it's >50 and <75 then with orange when its greater than 75. I've created a new measure called "color measure" and have tried using a IF statement ( I need to additional conditions later on).

When I just return the number from the IF it returns the correct number;

Color Measure = 
     VAR _per = [Learning Percentage Completed]*100
     RETURN

     _per

But when I try comparing the numbers they are all orange when only 84.59 should be orange.

Color Measure = 
     VAR _per = [Learning Percentage Completed]*100
     RETURN

     IF(_per >50 && _per < 75, "Red","Orange")

This should be pretty simple but what am I missing?

Thanks
