trouble is the door still opens when you press on the door itself. I dont really understand the GetSender ID reference. Any help would be great. Thanks.

Since the activated code has the line:
if (GetSenderID() != 0) return;
That means that if the senderID is not equal to 0 then the cog exits, and the door is not opened.

So leave everything the same BUT in your symbols section add a linkid for the DOOR as so:
Code: 
thing       Door   linkid=1

Since the id for the door is now 1 and not 0 (or lacking) then touching (activating) the door won't cause it to open. Since the switch lacks a linkid it is the same as 0 and will activate the door.

The other way to do this which is probably what I would actually do is have in symbols:
Code: 
thing       Door   linkid=0
surface     switch linkid=1

and change the line in the code section to:
Code: 
if (GetSenderID() != 1) return;

This is better because if you add other things or surfaces to the cog, then the switch will still be the only thing that activates the door.

OK, so far so good. The suggestions work BUT theres a problem. As long as you just use the switch it works fine. If you activate the door itself the door doesnt open BUT from then on not even the switch will work! This seems strange to me. Is it some c/s thing?

You see the lines directly after the activated message? 'If (rotating) return;
roating = 1;' Put those after 'if (GetSenderId() != 1)' (I assume you made the changes already suggested.)
That will fix your not opening later problem.
Heres what was happening:
When you activated the door, the variable rotating was informed that the door was opening and set accordingly. Then, getsenderid shut down the code before the doors actually began to move. Since the doors are in fact not moving, the arrived message nor blocked message are never called and thus rotating is never reset to 0. When you activate it another time, the cog thinks the door is in motion and stops.

Here is the completed cog, atleast how I would do it:

At least you're modest.
