how to connect external crystal oscillator with p89lpc936?

[sri]

Hello,
I have problem in programming with p89lpc936. The internal RC oscillator type of programs are programmed well, and working properly. But when I choose the external oscillator, problem occurs. In this manner I have lost 14 IC's.

herewith i have attached my problem detail.
The error message image also attach with it.

Please help to rectify my problem.

Put a scope on the XTAL pins - do you see sine waves? What frequency are they? Are they clean?

Put a scope on the RxD and TxD pins. Do you see the 'U' going in from Flash Magic and nothing going out?
