TypeError: Error #1009

[xvkarbear]

I don't know why this is not working.

I have a short quiz where in step one, the user clicks a button that populates text in a dynamic textbox. Then in step two, they do the exact same thing again.

I've done research that suggests I'm getting this error because something is not loaded or something is not on the stage, but all of the items are on the stage and I'm not loading anything externally. I've narrowed it down to my first set of event listeners, but they all look normal to me.

Here's the code (forgive the mess, there's probably an easier way to acheive what I'm trying to do, but I'm not versed enough to do it) and the fla:

Yup. I did that. That's how I narrowed it down to my event listeners. It specifically points out my first one:


scfor.addEventListener(MouseEvent.MOUSE_DOWN, optfork1);

but it looks okay to me.

[senocular]

if you trace scfor before that line, what do you get?

[xvkarbear]

if you trace scfor before that line, what do you get?


yesno.text = " ";
mycontinue.x = -1000;

trace (scfor);

scfor.addEventListener(MouseEvent.MOUSE_DOWN, optfork1);
scbut.addEventListener(MouseEvent.MOUSE_DOWN, optbutk1);
scso.addEventListener(MouseEvent.MOUSE_DOWN, optsok1);gives me:


[object SimpleButton]

[senocular]

And that was the line that the debugger told you was causing the error?

[xvkarbear]

And that was the line that the debugger told you was causing the error?

Yes. If by telling me, you mean there was a golden/yellow arrow pointing to it.

I need to point out that I don't get that error when I run it. It's only after I get to the point in the animation where they press the nextscenek1 button.

[senocular]

if you're going to another scene then its possible scfor will go null. Is the trace you posted the trace before the error occurred? That's the important one.

[xvkarbear]

if you're going to another scene then its possible scfor will go null. Is the trace you posted the trace before the error occurred? That's the important one.

yeah the trace is before the error occurred. here's the whole thing:


[object SimpleButton]
(The following doesn't appear until I click the button)
null
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at eng100_independentclause2_fla::MainTimeline/frame1()It doesn't seem to care if I'm going to the next scene or a frame within the current scene gotoAndStop(5) or gotoAndStop(1, '02'). The same error occurs.

[senocular]

yeah, because it's null - see the null trace? That's the error. You're running that code when scfor is null. You either need to not run it, keep scfor from going null (removed from timeline?) or figure out whatever other logic is necessary to make it work
