What am I doing wrong with my holo script?

Okay, I have a training holo script that I wanted to change a little, and so I changed the keyvals that are said in the chat to load the map, and then I changed the name of the maps in the lighting to match the keyvals, but when I test it, the map will not load when I say the keyword combination "simulation initiate S-57" or any other map. What have I done wrong?
