BowScore (One Command)

Hello guys! Click here to get the command
Today i have another aweosme one command block creation!
since i had a great responce on the previos comand i made this!

Okay so! what is it?
The command will spawn in a structure full of commandblocks!
these command blocks will add:
-A Zoom in bow
-A ScoreBow
-A Spawn Target egg (spawns a giant target)
-A Show Score egg (tells you what your score is and how many arrows you have used)
-A Reset Score egg (sets your score and arrow count back to 0)
-A helpful GUI
-A Scoring system for
     -Iron block (1 point)
     -Gold block (2 points)
     -Diamond block (5 points)
-Custom Targets

With player compatability in mind i made it so that any iron,gold or diamond block will add score so you can make your own targets!

Well thats about it guys! thanks for taking your time to read this!
