Problem with stage and Error #1034

Question

Hi!
Well I'm newbie in AS, writing it only for a 5 days and I've come across error which gives me a lot headache. I was searching for solution to it for quite some time now and didnt understand what I suppose to do with solution.
So, here is my problem if someone is willing to take a look at it.
Error:
TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Stage@ef6fb51 to flash.display.MovieClip.
at Association_fla::MainTimeline/frame30()
at flash.display::MovieClip/gotoAndStop()
at Association_fla::Association_12/prikazi()
at MethodInfo-32()
I have a lot of layers and movieclips inside my fla and so pasting all of my code isn' t an option, cause there is a lot of newb, memory wasting programming it could take hours for someone to look into it.
Problem here is, if I understood it right, that my stage isn't a movieclip as I referenced it, most probably in this section of code:
MovieClip(parent).gotoAndPlay("result");    //  in  stage / association_mc
Didn't have that error while doing same thing in other movieclips like:
MovieClip(parent).gotoAndPlay("home");  //  in  stage / instructions_mc
And last question is: How can reference my main stage? I'm using MovieClip(parent) to get to it, but I see that everyone using just stage object from Stage class
Thank you in advance!

Answer 1

also reports call to undefined method :/
1061: Call to a possibly undefined method gotoAndPlay through a reference with static type flash.display:DisplayObjectContainer.
edit:
After numerous checking code all over again and testing and tracing everything i found out that problem occurs when going to result label at Frame 31 when playing the result_mc movie.
going from different movieclip to it gives this errors

edit2:
resolved !
found on one forum this answer, maybe it will help someone else
I've just had the same problem myself. A bit of detective work revealed that it has nothing to do with the code, but occurs when:
The swf is being run from a remote server.
You have a custom class on the stage which has an instance name.
The class is NOT declared as "Export in first frame".
An instance of the class doesn't appear on the first frame of the movie.
So the solution, in my case, was just to tick "Export in first frame" in the library symbol linkage options. This made everything work fine, but if anyone knows why this is then I'd be interested to know.
