Some help with even.target and coloTransform

I create a grid of squares using XML. The XML contains color values for each square. A for loop is used to run through each node, create the square with the correct color. Once the squares are generated I want to click on them and get the colorValue and change the color of another larger square on my stage. For some reason I can’t get the value to pass from the XML function to the addEventListener.

I attached the fla and XML file I am using, need some help.:ko:
