Hyundai getz 1.1 2005 gearbox troubles
 

Hello everyone!
I just bought this car with 77k mile on board.
No experience, I'm a new driver, I have gearbox problem.
While I'm driving i can't shift the gear from 3 to 2, or 4 to 2,to be able to shift it I have to go for 1 the I can shift it to 2. But this is happening only in driving. It seems to be stuck, it doesn't shift.
While the car is park with or without the engine on, it works smoothly, can someone give some ideas, answers? Thank you!

Any solutions to this problem?
