Basic PIC circuit acting weird

Hi

I'm following a basic PIC tutorial. I've assembled a circuit on my bread board to flash an LED. I'm using the PIC 16F886 with a 5V AC to DC converter (500 mA max).

The Setup:
5V going to the Vdd
5V to MCLR through 11.5 kOhm resistor
Vss to ground
5V to RC oscillator w/ a 11.5 kOhm resistor in series w/ a 27 pF capacitor to ground
OSCin is connected to the RC oscillator between the resistor and capacitor
220 Ohm resistor from port B to an LED to ground

The problem:
The circuit doesn't work unless i'm physically touching the LED wire or the resistor coming to it. I checked my connections with a multimeter but they seem ok. The port doens't seem to output voltage UNLESS i'm touching it.

LOL this is driving me insane. Any ideas on what's happening.

Thanks

Post your code, PIC number. Do you have a regulator in your power supply? Capacitors ? Have you set the TRIS and PORT registers? Have you set the config fuses? Are you using Resistors to tie the unused ports to either ground or VCC ?

your oscillator does not work! It start oscillating when you introduce disturbances with your body antenna. Replace oscillator with something that surely oscillate as a ceramic resonator.

you're right, i hadn't set the right oscillator setting on the pic.
