TypeError: Error #1006 - Removing MovieClip from the stage

Question

I have a movie clip that is called to the stage and once the movieclip is finished it calls a function that removes it from the stage. The code works but I get an error message about 4 seconds after the movie clip ends.
Here’s the error message:
TypeError: Error #1006: exitWordMicroscopic is not a function.
                at ASvocabulary_microscopic/frame110()[ASvocabulary_microscopic::frame110:1]
Here’s the stage code:
//************************Removes the movieclip from the stage and enables the button.*************************
function exitWordMicroscopic():void
                bnt_vocab_microscopic.mouseEnabled = true;
                removeChild(word_Microscopic);
//******************************Stage buttons**************************************
stage.addEventListener(MouseEvent.MOUSE_DOWN, goButtonsHomeRead_1);
function goButtonsHomeRead_1(event:MouseEvent):void
                //Vocabulary buttons
                if (event.target == bnt_vocab_microscopic)
                                bnt_vocab_microscopic.mouseEnabled = false;
                                SoundMixer.stopAll();
                                addChild(word_Microscopic);
                                word_Microscopic.x = 47;
                                word_Microscopic.y = 120;
Here’s the code inside the movie clip. This is what the error message is referring to:
//****************** Calls function to remove itself from the stage****************************
Object(parent).exitWordMicroscopic();
What am I doing wrong?

Answer 1

Here' how the code looks now:
Objective: To remove the current movieclip while it's playing so that it does not show on the next (or previous) frame.
Here’s the stage code:
var word_Microscopic:ASvocabulary_microscopic = new ASvocabulary_microscopic();
//Removes the movieclip from the stage and enables the button.
function exitWordMicroscopic():void
    bnt_vocab_microscopic.mouseEnabled = true;
    removeChild(word_Microscopic);
//******************************Stage buttons**************************************
stage.addEventListener(MouseEvent.MOUSE_DOWN, goButtonsHomeRead_1);
function goButtonsHomeRead_1(event:MouseEvent):void
    //Vocabulary buttons
    if (event.target == bnt_vocab_microscopic)
        SoundMixer.stopAll();
        bnt_vocab_microscopic.mouseEnabled = false;
        addChild(word_Microscopic);
        word_Microscopic.x = 47;
        word_Microscopic.y = 120;
        word_Microscopic.play();
//This button takes the user to the Main Screen
    if (event.target == bnt_ReadGoHome_1)
       // exitWordMicroscopic(); [If I use this function I get this error ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.]
        SoundMixer.stopAll();
        gotoAndPlay("1","Main");
        stage.removeEventListener(MouseEvent.MOUSE_DOWN, goButtonsHomeRead_1);
//This takes the user to the next frame.
if (event.target == GoNext_1)
        SoundMixer.stopAll();
        gotoAndPlay("2");
        stage.removeEventListener(MouseEvent.MOUSE_DOWN, goButtonsHomeRead_1);
Here’s the code inside the movie clip.
//****************** Calls function to remove itself from the stage****************************
Object(parent).exitWordMicroscopic();
