I realize that this question should have a simple answer, but it seems that the application is more complicated.

I would like to use an "IF" statement to change the fill color of a bar in a bar chart if the sum of "Sales" for an item is above the 10.

To get the value of each item's sum of sales simply FIRST(SUM(Fields!Sum_Of_Sales)). But how do I apply this value into a condition that will change the color of the bar?
