My GUI rockets(Texture) doesn't disappear when I fire the Rockets?

The GUI rocket textures (there are 21 pictures of rockets which I put into each of the element variables in the FPSplayer script). But nothing happens. When I play the game all I see on the screen is a full clip of bullets(rockets) Why don't these GUI textures disappear one bullet at a time. Do I need another script? Currently I have in my Hierachy: GUIHealth, GUI text, GUI overlay and GUIRocket21. Under GUI text, I don't have any scripts. Under GUIrockets21 I have GUITexture and the DrawRockets script. Under GUI overlay I have GUITexture and no scripts. Under my FPS controller I have the FPSPlayer script. Within this script I dropped my GUItext into the Bullet GUI variable, I dropped my GUIRocket21 into the Rocket GUI variable and I dropped my Healthbar GUI in the Health Gui. The health bar works perfectly. As damage occurs the health progress bar slowly disappears as my health depleats. Why don't my bullets or missles disappear? Anybody got a suggestion or a reason why? Thanx
