Import and Globals. Whats wrong?

Import "Globals.bmx"
Main-Module can read all Globals declared in that Module

Import "SomeTypes.bmx"
Can not acces/read Globals declared in "Globals.bmx"

"Globals.bmx" just looks like:

Global Width:int=1024

Why its only a Global for the Main-Module and all other imported modules ignores it?
Puplic or Private didnt help.
What did wrong?
