ICM HW3 Debugging Color Change Not Working

//only change the color when not dragging and when it passes the stop angle
if (mouseAngle >= stopAngle || !dragging) {
	changeCol = false;
} else {
	changeCol = true;
}
//when slider position hits stop angle
if (angle > stopAngle) {
	//change the color
	if (changeCol) {
		h += 20;
		changeCol = false; 
	}
	//reset the angle
	angle = 0;			
	//reset the color to beginning
	if (h >= 360) {
		h = 0;
	}
