Xbee shield and interrupts on Arduino UNO

Hi.
I have been unable to use interrupts on the Arduino UNO when the Xbee shield is connected. It's not an issue without the shield. I understand that the Xbee shield has a switch to choose between pins 0 and 1 or pins 2 and 3 for serial transmission, and I have it set up to pins 0 and 1, so that should not be interfering with interrupts on pins 2 and 3 on the UNO. I'm completely stumped as to why I am having this issue...
Any help or suggestion would be greatly appreciated!

In what way does it not work? Can you read the pin states of 2 and 3 with digitalRead, while it is attached and manually applied voltage levels to it? Does that work normally as it should?

If you meant the Sparkfun Xbee shield then there are solderjumpers between the switch contacts and D2 and D3. Those might not be conducting on your's.

Might I remind you that you have not shared any code. So how are we to find a fault in that? Or know what you are actually trying to to with interrupts.
