Ok let me see if I can help...

I just started mapping too and have had some probs as well. Im going to assume your using MOHradiant for your mapping.

Lets start with the easy part...If you want to make a hidden door all you have to do is chose the same texture for the door as for the wall you want to hide it on. The texture doesnt affect the operation of the door.

If I was you I would start from scratch with the door.

Delete it and start over (Just the door not the map).

Assuming you have done that, here goes...

Create the block for the door...

choose whatever texture you want it too look like...

decide which edge you want the hinge at and create another block there for the "hinge"...

If your door is one grid square wide and 6 grid squares long and 8 grid squares high create your "hinge" as one grid square wide and one grid square long and 8 grid squares high.IN THE SAME SPACE AS the first grid square of your door on the side that you want the "hinge" so that they look like one block...

Now make sure just the "hinge" block is selected and select the origin texture for the "hinge" (located in the "common" textures)

Then as MPOWELL1944 said: Again with just the hinge block selected Place a func_rotatingdoor on the hinge of the door, by right clicking on the map grid and choosing func-->rotating door Have the func_rotatingdoor selected and hit N. Enter alwaysaway for the KEY and 1 for the VALUE then hit enter. If it is a metal door, enter doortype as the KEY and metal for the VALUE. If it is wood, leave it alone. When you have added those values, hit N again.

Your door should now work.

Hope this help a bit more.
