check for null maybe. If something doesn't exist it would throw a null.

 How do you test (without warnings and errors) if a

 For example if there is a vars.myname set?
 (I.e. otherwise vars.myname would be undefined - according to
 http://help.adobe.com/en_US/AS3LCR/Flash_10.0/package.html#undefined )

 Is the following correct:

  if (vars.myname != undefined)

 Can you compare undefined to undefined?

 Thank you

Hi Alex,

You could use a 'try/catch' block...
e.g.



try {
if (vars.myname != undefined){
// do something
}
} catch (e:Error) {
trace(ERROR: your error info here);
}
