pin assignments to GPIO of Cyclone II

I am facing a problem regarding pin assignments. I tried to assign an on-board switch to an on-board LED.

Similarly, I assigned a switch to external pins: GPIO 0 or GPIO 1 plug, but nothing is working ---means I cannot assign any IO's to external peripherals through these plugs.

INTERNAL : Switch ------- Internal ------ LED works fine LED lights if switch on and vice - versa

EXTERNAL : Switch ------- Internal -------LED doesn't work (Switch is connected to 3.3 Vdc from the board)

3.3V ____/ ________............._____LED.

PLEASE can you help me. Can not find any reference to this problem in manual ---- Pin assignment as per the instruction.

With kind regards,
