I have been creating a list of new ideas to use in the map I will be making and I tried to test one of them which was to put a round door on the roof and set it with a timer. All was looking promising until I pressed the switch and the door opened in a funny way...the left door went up and the right door went down. Im guessing this is because the way it is made, it opens about an axis and therefore when I flipped it to be on the roof, it wanted to open the wrong way. Is there any way of fixing this or will I have to rethink the idea for the room? Also just so you know I was using the round door prefab in the CP4P file.
Any suggestions?

This is the problem with prefabs.. people spread them away in their maps but don't have any idea of how it works. In you case, there's nothing more to do than opening each door's properties, and changing the movement direction. Beware: the door isn't what you see (the circular model), it should be inside, it's a func_door block entity.

It sounds as though you need to change the Pitch value of your func_door's 'Move Direction (Pitch Yaw Roll)'.

I don't know exactly how you have it set up, but a value of 90 or 270 should do it, depending on the door.

Thanks for the advice, I will try that now and then post the results.

While prefabs are certainly excelent time savers, and help keep consistency through your map I'd still really reccomend at reading up on a few tutorials on making things from scratch - a grip of how it works will really help your debugging and problem solving

For some good tutorials any of these:

the pitch yaw roll has a value of 0 180 0, im guessing I just swap the 180 with 90 or 270 and see what happens?

The line on the dial of the Pitch, Yaw, Roll arrow shows the direction the door will move in the top down view, you can set this in the direction you want, or use the drop-down box for up and down. Goodluck

Ok, it worked, the roof door now opens fine, though I have run into a new problem, I'm guessing it's also something to do with the pitch yaw roll because the problem is that a door I have placed is opening very strangely (one side of the door goes forwards and the other goes backwards). They dont even go right or left or up or down, it is wierd. I might just remake a door but before I do I would like to fix it so I know what's happening.

Yea, sounds like i's still just your pitch yaw roll are screwed up. No need to make a new door, just fix the values.
