Cheat Code help please?

[Altone]

Just joined this forum, so if I hope you bear with me for a while.
New to the gaming scene and I need a little help. I have two new games that I would like to enable the cheat codes to, and I don't know how to do it. The Games are Call of Duty and Medal of Honor. I have downloaded the Cheat Codes from Megagames, printed them out, and I am stuck where it tells me to 'Create a shortcut and edit the properties of it and add this after all the other stuff: "+setmonkeyty 0 +set sv_cheats 1" I am refering to Call of Duty here. Could someone explain 'simply' what this means I have to do? I can open the console in the game ok, but I think I need to do this shortcut bit. If I type in the console 'give health' it says its an incorrect command.
Medal of Honor cheat code says 'Start the game with the [folder path ] \mohaa.exe' +set ui_console 1 +set cheats 1 +set thereismonkey 1 command. What is that all about?
Start a game and press ~ to display the consol window. I cannot open the console window in this game when I press ~.
Ok! I know you are all laughing, but stick my dummy back in my mouth and make me a happy bunny again. Help please? ( The Germans keep killing me!!!)
