how do I use global variables concept? [Solved]

[jssjr90]

Created upon use? So uhh im starting to get it but some things i dont get, like that created upon use thing. and is there some other place you supposed to put the main global variable that you declare other maps read it? becouse it would not make seance to put it in the normal map script file.
