Your players are completely wrong.^^
Go to Edit->Edit Player List and delete PlyrElves, player1, player0002, PlyrMordor.
Afterwards just use the "Add skirmish player" button. This adds all the players you need, the named players are not needed and only take space (there is a maximum amount of possible players, therefore I'ld delete them).
Now you can just put your script in the PlyrCivilianfolder and say
The map is revealed inside area 'Reveal' for Player '<All Players>'.
Or you can just select the Player_1 from the list.
Never use such self created player names in skirmish, if you don't know exactly what you're doing. In 99% of the times things don't work as you intend and in 99,9999% you can make everything with the normal players which are added with the button in a smoother way. So don't use them until you know a bit more about the worldbuilder. Until then just use the normal skirmish players.^^
Another note:
Please test all your bridges. I don't know if those bridges count to the normal limit, but there is a limit of bridges which is set to ~7. Some bridges don't count for it, but please test all of them, as it could happen that they don't work.^^
