Telltargeting does not seem to work for external use

Hi all

I got this slight problem, I have created this movieclip called “start” which as a button on the end frame which will play a frame on the external movieclip which is called “into” here is the AS for the button

on (press) {
tellTarget ("_root.intro") {

When i publish this the fla into a swf it works as it should.

My problem that I am having is that when this swf is loaded into an external swf this telltarget function does not appear to work anymore.

I am assuming that I may have to change the code somewhat so that this feature will work. otherwise I can only guess that there is something wrong with my main swf file (the one where this is beening exported too)

Any hints, tips or suggestions will be apprieciated.
