Switcher CAD III, higher frequency

hi everyone, I'm having some trouble with this here circuit and SW CAD III. Why can't i get this circuit to operate @ somewhere between 88-108 MHZ??? Ive sat and fiddles w/ it for an hour and just cant get it 2 work!!! Any suggestions?

My advice is to stop playing with simulators and build the circuits, as I see it simulators are mostly a waste of time - all the related threads on these forums are about how to modify a design to make it work under a simulator, if a correct working design won't work 'as is' under a simulator the simulator is a total waste of time and money!.

I have built this circuit. the reason that i am trying to simulate it is cuz i dont have an oscilliscope, and id really like 2 c what is going on in there, and see how different values affect it.

Jsut throw in 100 times bigger values (assuming you are talking about C1 and L1).

Oh yeah, 1 thing that i forgot to mention is that i did get it to work by throwing in bigger values like u said panic, but I wanted it to be high frequency . . . just like my circuit. if it is lower frequency, then the results wouldn't pertain to my circuit, or would they?
