CLUTCH NO GEARS ENGAGING

The gears change all okay without touching the clutch, put it in Reverse and you can see it trying like a snail pace but forward gears nothing. Rev counter sits at 10 and does not stall if clutch released. No leaks and Brake fluid reservoir full.

Any ideas would be amazing, got a passion for these Astra's and want to get her back on the road and spend some money on doing her up.

I hope its not a new gear box..
