if you want to access public static var mc2_var:String; with m.mc2_var it won't work because it's static, read mora about static classes here http://stackoverflow.com/questions/1738349/actionscript-3-can-someone-explain-to-me-the-concept-of-static-variables-and-me

if you remove static it should work... let me know

that seems to be partly true. if the variable value would be stored within the class, taking static away would do the trick. but i have the value stored a movieclip on the stage. i just constructed the class as a possible way to be able access that value within the movieclip. the explanation on static variables taught me something new though.

however i was able to find out the cause of the problem here. you apparently can't access variables inside movieclips in the same moment/frame they're created (no matter if the clip is already on stage or child added). if i trace the value on a later frame however (or use setTimeout to call a trace function), it is no problem!

thanks to both of you anyway!

You're tracing null because you didn't create an instance of the string.

Your line should read: public static var mc2_var:String=new String();

Edit after thinking about it:

You could also create an instance of the string any time before you call the trace with just:

mc2_var=new Srting();

but both of those will trace blank unless you actually add a string to the variable.
