Basically I placed my textures and everything on the window and now I want my sphere or the ball to move left or right, I have the special key code, etc but for some reason still my ball isn't moving left or right!!?

Why is this happening please check my code

I WILL HIGHLIGHT THE IMPORTANT MOVEMENT RELATED CODES IN BOLD

Am I putting the special KEYS FUNCTION CODE in the wrong section?

Please I've wasted over 2 HOURS TRYING TO FIGURE OUT HOW TO MOVE THE BALL left or right! I USED MY OLD CW CODE TO MAKE A SPHERE AND MOVE THE BALL AND IT WORKED BUT FOR SOME REASON IT DOESN'T WITH MY CODE WITH TEXTURES...
