Gear motion analysis in COSMOSMotion 2007

[djhammerhead]

Hi, I would like to analize in COSMOS 2007 an assembly of gear mechanism (gear and rack). I have made all the mates, which are necessary between the parts, but when I started IntelliMotion all the parts are scattering in all the directions. I have tried several times between which parts to be the motion, but every time it is the same and I could not understand where I am wrong.

Here is a picture of the assembly:

And here is the assembly files:

Thank you in advance!
