How do you create and impassable connection?

[CSJ]

Pretty much the same idea as making a connection between Korea and Japan but in this case Canada and Germany. What exactly would I have to edit to put this in?

edit: As it directly has to do with this question, can anyone tell me why this event won't fire?

event = {
id = 1000010
random = no
country = CAN

name = "Germany and Austria joins us."

action_a = {
command = { type = addcore which = 302 }
command = { type = addcore which = 308 }
command = { type = addcore which = 473 }
command = { type = addcore which = 382 }
command = { type = addcore which = 80 }
command = { type = addcore which = 81 }
command = { type = addcore which = 82 }
command = { type = addcore which = 83 }
command = { type = addcore which = 84 }
command = { type = addcore which = 85 }
command = { type = addcore which = 86 }
command = { type = addcore which = 87 }
command = { type = addcore which = 88 }
command = { type = addcore which = 89 }
command = { type = addcore which = 90 }
command = { type = addcore which = 312 }
command = { type = addcore which = 313 }
command = { type = addcore which = 314 }
command = { type = addcore which = 315 }
command = { type = addcore which = 374 }
command = { type = addcore which = 375 }
command = { type = addcore which = 376 }
command = { type = addcore which = 76 }
command = { type = addcore which = 67 }
command = { type = addcore which = 75 }
command = { type = addcore which = 74 }
command = { type = addcore which = 66 }
command = { type = addcore which = 298 }
command = { type = addcore which = 299 }
command = { type = addcore which = 300 }
command = { type = addcore which = 301 }
command = { type = addcore which = 396 }
command = { type = addcore which = 297 }
command = { type = addcore which = 310 }
command = { type = addcore which = 309 }
command = { type = addcore which = 311 }
command = { type = addcore which = 373 }
command = { type = addcore which = 377 }
command = { type = addcore which = 460 }
command = { type = addcore which = 461 }
command = { type = addcore which = 462 }
command = { type = addcore which = 463 }
command = { type = addcore which = 464 }
command = { type = addcore which = 465 }
}
}

There are no start or end dates for your event. As for getting impassable land connections, check adj-defs.csv in map folder. There are plenty of impassable land connections already so use them as model.

As far as the event goes, I know it's not a lack of dates. All the other events I have created have never required them. I want to fire this from the console only.

it misses a description maybe? no idea if they are a must but i aways add them

Well, I'm not sure what the original problem was but I just added the necessary details (IE: adding the cores) to pre-existing event I made as an action_b, works nicely. Thanks for pointing out where to go for the province connections though.
