IDEA didn't find classpath ?? plz HELP!!

Hello ....

I have made a project in intelliJ IDEA 3.0 with all my classpaths defined for the source files. Classpaths are all valid and i did work with my classpaths in other GUIs and with options on console as well. But, none of my classes are able to compile with IDEA classpath settings. I don't know why this is happen, as i have followed all the necessary steps to setup a project in IDEA.

any help would be greatly appreciated.

thanks, Raheel.
