Glass showing solid (Blender render)

I am working on this project, and am not going to let this stop me (not finished modeling), but I have discovered a problem with my glass material.

The foremost glass shows perfectly well, but when there is a piece of glass showing though another piece of glass, the one in the back appears solid. I have a few tests I did to make the problem more apparent.

Try to increase the Depth value of the ray transparency. Don’t forget to enable transparent shadows for the materials.

I thought it would be something quick, and it was just the ray depth. I jacked it up a bit and it works perfectly now, thanks for the help.
