Particle system won't go behind other drawing layers

Ok, all I want to do is to have my particle system located between drawing layers.

According to this site it tells me that by putting a peg in the right port of the particle visualiser I can move my particle system behind other layers. My problem is that when I try to move my system using this peg, nothing happens. I plug it into the left peg and it moves the particle system up and down, and along the z axis, though it is still visible through all the other layers.

Any ideas why this might not be moving my system?



Sorry, figured it out. Didn’t realise the right port only went along z space and not through the x and y axis. As there was no background behind the particle system I didn’t think it was moving as it wasn’t going up and down, though it was moving through z space. Doh.
