Top Down BP Based Scene - Camera Rotation

Hi everyone,

I have a very noobish question concerning something I’m trying to achieve with Blueprint.
I took the default top down scene in which I put the camera in first person view. So the character can now move by clicking.
What I would like to add to this is the ability to rotate while pressing right click, I tried, searched on the forum and I found this :

&d=1407375895

It looks pretty correct but it doesn’t work on my scene I tried to use it on “MyCharacter” BP (the one with the camera) but also tried on “MyController” BP
But none of them change a think I still can’t rotate juste move by left clicking.

What am I doing wrong?
Thanks in advance.
