wobbly toilet, tightening nuts not working

The basement toilet was leaking, so I got a wax ring to reseat it. When I tried to undo the nuts, the screws snapped off - they had rusted out. When I removed the toilet, I found the screws had been set in the cement. I hacksawed them off and went to the plumbing supply store. They sold me a nifty PVC flange that had a compression rubber ring. I got out the drill and a masonry bit and installed the flange securely to the cement floor. Believe me, it isn't going anywhere. I tightened the compression screws to seal off the gap in the pipe. I then fitted the wax ring to the underside of the toilet and placed the screws in the proper place in the flange. I placed the toilet on the flange and wiggled it like the ring directions advised. I tightened the nuts on the screw and the thing wobbled like mad. I tighten further, still wobbles. I noticed the washers had been indented from the pressure of the nuts. Still wobbles. What can I do to get this toilet to stay still?? Please help!

Buy some white nylon wedge shims and shim it on the appropriate side and cut the shims flush to the edge of the toilet.

Along with the shims, you can also caulk it to the floor. Just leave a gap behind the toilet so you will know if there is a leak. It is more than likely it is wobbling due to the flexibility of the pvc. Good luck!
