What's wrong with this command block code? [duplicate]

I am trying to check if I am in a spesific area and I use command blocks for that: This is the code I use:

testfor @p[r=4,name=<\miner11crafter>]

It should be right acording to this syntax I found on the gamepadia:

testfor @p[r=5,name=<\owner>]

\ is neccesary for the formatting in SO otherwhise you can't see my name and stuff. What am I doing wrong ?
