Error opening external swf

programming flash
1

Hi,

Got a question, should be pretty simple…

I use this script on a button:

on (press){
    loadMovie(testfilmpje.swf, this._parent.detaillijn_mc);
}

The returning error is:

Error opening URL ‘file:///E|/School/Afstuderen/Prototype/undefined’

The “testfilmpje.swf” is in the Prototype folder.

So, what’s wrong??
