To me it sounds like your pilot light on the fireplace is out. That could happen from a strong wind coming down the chimney or a strong breeze in the house from a fan. Check your pilot light and be sure to have the gas off before lighting the pilot light if it is out.
your pilot generater or thermocouple is probly bad
If holding the controls in the LIGHT position for about 15-30 seconds does not keep your pilot lit, there is probably a problem with the thermocouple. That is the small tube that the pilot flame touches. Be sure it is not bent, and being missed by the pilot flame. They do go bad, and require replacement.

Check your instructions, Usually you have to keep it on pilot mode for 30 seconds then you should be able to turn it to on without the pilot flame going out.
Most makers recommend that IF you shut down a pilot light for the summer, you have the system inspected and serviced before restarting. The pilot light also serves to drive off moisture from your controls during summer, preventing corrosion. See what YOUR manufacturer suggests.
Maybe. Get the instuction manual for your fireplace. Depends on whether the OFF is master valve, or secondary valve. If no manual, hire a gas service company to do it, and show you how.

The Pilot or O.D.S. is clog'd
Just a guess- but most have a sensor known as a thermocouple. This detects the heat of the flame of the pilot light, and keeps gas from flowing if the pilot light is not lit. check that your pilot light (a very small flame) is burning, and that the flame heats a small metal tube- about as big as a wooden match. If pilot is out, get it lit, and let burn for 5 minutes, and try lighting fireplace. If it still will not stay lit, the thermocouple may need replacement- they DO wear out. Check with your local gas appliance repair service. While they are fixing it, have them show you correct lighting process.
