You may need to adjust your clutch or replace your clutch.
The clutch pedal must be fully depressed ... could be the switch that senses travel for that pedal needs to be replaced or re-aligned.
Your clutch is not disengaging completely, you may get a little more life out of it by adjusting the pedal travel but in the end you will need to replace the clutch

There are three main types of gear shifters for vehicles: manual, automatic, and semi-automatic. Manual shifters require the driver to manually change gears using a clutch pedal and gear stick. Automatic shifters change gears automatically without the need for manual input. Semi-automatic shifters allow the driver to manually shift gears without a clutch pedal, using paddle shifters or buttons on the steering wheel.
if there's a middle pedal you're in a stick shift and you'll need to know how to use the pedal on the left (the clutch) to shift gears
When Dee learned how to drive with a stick shift, the manual action of the clutch helped him move between the gears.
if its hydraulic there could be air in your line. bleed your clutch and refill.
the gears probably arent meshing when you change gears. Either the clutch is bad, or you need a new gearbox.
the closest vw beetles came to having an automatic transmission is called an auto-stickit has a gear shifter like a manual trans, but no clutch pedal. you push down on the stick, and then shift gears.
