'message', isn't that supposed to be text?
var/LoginMessage = input(usr,"What do you wish to say?","Edit Login Message") as text

If you want to modify the previous loginmessage, you need to supply it as a parameter to input():

var loginmessage = "Hello, world!"

mob/verb/EditLoginMessage()
   var newmessage = input("New message!", "Edit Login Message", loginmessage) as null | message

   if (length(newmessage) > 0)
      loginmessage = newmessage

message is a valid input() specifier. It displays a multi-line text prompt, rather than the single-line one that text shows.

My snippet was just a quick example. Look at how I set input() up: I pass the loginmessage variable as the last parameter to it.

It was an example. You only really needed:
1. The third input() argument for the default value.
2. The "as null|message" for the Cancel button.

In the future, don't copy/paste code and expect it to work unless the poster says you can.
