Commands for Smoke Grenade! Test it on your single player world!

Hello Everyone! I hope you saw my previous thread called "New Equipment: Smoke Grenade" if not you can watch it here. If you want to test it, you can follow these steps on your single player world:
Step 1. Create a single player world on creative.
Step 2. Do /give @a command_block
Step 3. Then do a redstone clock if you don't know how to go here
Step 4. Then the clock is going to activate a commandblock, in the commandblock type /testfor @e[name=Smoke]
Step 5. Then after the commandblock set a redstone comparator to a repeater.
Step 6. The repeater is going to lead to a commandblock, type this in the commandblock: /execute @e[name=Smoke] ~ ~ ~ /particle smoke ~ ~ ~ 5 5 5 0.05 1000 @e[name=Smoke]
Step 7. Set one repeater from that commandblock to another commandblock that does: /kill @e[name=Smoke]
Step 8. Drop a item that you have renamed to Smoke
If you get problems contact me! I will probably make a video to this soon! To increase the effect change the 1000 in he 2nd command to something bigger and smaller to decrease it.
Good luck!

I will add a video and a picture how it will look and where the commands should be.
Here the first picture is, the on that show you how it should look, i will make one in minecraft when i get home... Im making this thread on my iPad.
