Lilypad Xbee xctung issue

I am having alot of trouble reading and writing an Xbee in XCTUNG using the lilypad Xbee. I have the xbee mounted on the Xbee lilypad, which is connected (+,-,rx, tx) to the Arduino Lilypad (+,-,tx,rx) which is connected to my computer via FTDI and mini USB. I know that the xbee module itself is working fine because I have accessed by mounting on my uno w/ shield. Why would this work on my Uno and not the Lilypad???

thanks in advance, this is driving me crazy
