how can i fix my 206 1998?

You should be able to fix this yourself,look down behind the engine near the gearbox should be two small selector rods,with small nylon cups that press onto balls,the nylon wears and these rods pop off the balls,to get home just pop the rod back onto the ball,may need a wee bit of pressure to click it back on,Iwould order both rods and fit them,have a lever of some kind to help you remove them and may need vice grips or strong pliers to help you fit them,good luck
