Passing Variables to from one SWF file to another

[stormshield]

Hello, I've been fighting with this for months and have always chosen to go some alternative way. So the thing is: I have a SWF that uses loadMovie to display another SWF.

loadMovie("file.swf",square);

That works fine. But I would also like to pass a variable to the other SWF (file.swf").

For example: so that I can change the value of a textfield.

Is it possible? I know it's not a basic question.

PS I tried to use question string in this way: loadMovie("file.swf?var=22",square). No luck.

Best regards,
Storm
