Doom 95 shareware

I can never get to the next level or whatever cause I can't find the "secret". What is it and where do I find it can anyone tell me. I'm obviously a newbee but I like the game and just find it frustrating that I can't get past this point. I get all the rest of the game except I can't get the secret before I open the final door and go to the panel in there. It tells me I have no secrets therefore I believe I can't go onward for that reason. I would appreciate any help on this as I can't find it in any of the help menu in the game.

you don't NEED to find all secrets to move on
