Yes, sounds like one of the "gates" is out of position or more likely the shift fork has come loose from the rail. Could be loose or just sliding on the shift rail so it will not move the gears.

OK. Thanks guys.

I had the same problem. The shifter boot had cracked and had let rainwater into mechanism, over time causing shifter to freeze up, so that you could only shift first and second. Remove boot, and you will most likely see the problem. Heat and lots of loose juice. Easy fix.
If doing what Doug says dose not fix it,the next place to look is the side cover and the detentes as OM was talking about.
Had one that jumped out of 1st gear,and a little loose juice and maybe a different spring fix it right up. At the time I was not hopeful about that little bit fixing it but that is all that it took.
