jQuery ZeroClipboard Doesn't work when I have followed the instructions

I have tried the sourcecode from http://www.steamdev.com/zclip/ by applying the file on the internet (http://testtesttesttest.site40.net/index3.html) but doesn't work despite that I have followed the instructions from http://www.steamdev.com/zclip/.

I gave a new try by using CDnjs (http://cdnjs.com/libraries/zclip/1.1.1) for http://testtesttesttest.site40.net/index4.html but the same problem still existing.

I also have tried this code from this webpage (ZeroClipboard - How to use) but the same problem iccur.

I don't understand why jQuery ZeroClipboard (http://www.steamdev.com/zclip/) doesn't when I have followed the instructions?

Thanks!
