How to fill in area on chart?

[lc130]

This is a screenshot from a chart. I'd like the area between Mod poor and Mod avg (upper and lower lines) to be one color or shade and another color or shade for Cons poor and Cons avg (inner lines).

Is this possible in excel 10? Can someone point to a tutorial?

I've uploaded the spreadsheet.

Thank you

Kelly

Maybe use Area chart
or
Fill Under or Between Series in an Excel XY Chart
