Dudley concealed cistern help

[genericguy]

I am an absolute novice (to put it politely) and am trying to sort out my toilet.
It suddenly stopped flushing today, the cistern is still filling up fine but the flush itself doesn't work, you can make it flush feebly by pressing inside yourself but I thing it needs a vacuum which isn't there.

The pipes inside were unattached when I opened it up, and I can not for the life of me work out where they should be connected.
This is what it looks like:

It has two pipes coming for the flush, one green one that connects to a plate with a clear pipe on the other side going to the right of the green part marked Dudley, I assume the other green pipe connects to the front of the plate on the other connector but no idea what goes where really :S
I have gooled extensively but can't find a decent picture anywhere, would be eternally grateful for any help.

*I've removed the picture as it was so stupidly large!

That's the biggest picture in the world!! Can't make head nor tail of it

Hopefully this is a bit better!

The clear pipe on top is the bit that's really confusing me, although other bots could be wrong too!

Thanks, I have looked at that, one of them does look like the set-up I have but none of the diagram show any of the pipes

Just to clarify, the clear tubing is not attached to anything (but it should be!). The green tubing could be wrong but looks right to me.

Did you look here?

If its a Dudley vantage there should be a green pipe and a clear pipe. Both fix to the push flush on the push button one is half flush one is full flush. Simples

Thanks to both of you, as this suggests the clear bit goes directly onto the flush. However the guide doesn't show the other end of the connection, the clear pipe has a t-connector in it so not sure which bit of that to connect and where?
Also where does the green pipe attach to inside the cistern?

I really apreciate the help though
