Broken regulator (?)

[bsnalex]

Maybe this is, or isn't the right place for this question.

I went to turn my gas grill on last night, and when i went to ignite, I noticed there was no gas coming through the burners. I checked the connections and could not hear or smell any gas coming from the rubber line-- and if I had, some would still be making its way through to the burners. I removed the regulator, rotated the switch a couple times popped it back on and still nothing.

Then when I removed the regulator again I noticed there was a rattling inside the regulator. Anyone know what this could be? If I could assume, it would have been part of the spring system that forces the gas can open...
