Weird error AS3. Term undefined - actionscript-3

Question

so I'm getting an error at line 342 which is
myTextField.text = object[curPart]["text"]
it says that a term is undefined. Tracing curPart gives me a null value, although in code that runs literally moments for that one, curPart is part3. Nothing changes it. This is what runs before it, a type writing effect function.
private function addCharackter():void
{
if (!textFinished)
{
// add the charackter to the Textfield
myTextField.text = object[curPart]["text"].substring(0,counter)
counter++
trace(curPart) // prints "part3"
// if you reached the end of the String stop Timer
if (counter == object[curPart]["text"].length+1 && !textFinished)
{
textFinished = true;
trace("Text finished:",textFinished)
clearInterval(sInt)
counter = 0;
if (object[curPart]["text"].indexOf("What do you do?") >= 0)
{
trace("H!!!")
choosing = true
createOptions();
}
if (object[curPart]["text"].indexOf("What do you do?") >= 0)
{
dead = true;
}
}
}
Another weird thing is that the error doesn't happen if I finish the type writing effect by pressing space which is done here:
public function onEnter(key:KeyboardEvent):void
{
if (key.charCode == 32)
{
if (dead && textFinished && !choosing)
{
curPart = object[curPart]["lastPart"]
textFinished = false
dead = false;
myTextField.text = ""
counter = 0;
sInt = setInterval(addCharackter, textSpeed)
}
if (!textFinished && !choosing && !dead)
{
trace(textFinished)
trace("finishing")
trace(curPart)
myTextField.text = object[curPart]["text"]
if (object[curPart]["text"].indexOf("What do you do?") >= 0)
{
trace("H!")
choosing = true
createOptions();
}
if (object[curPart]["text"].indexOf("You have died") >= 0)
{
dead = true;
}
clearInterval(sInt)
textFinished = true;
}
else if (textFinished && !choosing && !dead)
{
trace("Hi!!!!")
curPart = object[curPart]["nextPart"]
myTextField.text = ""
counter = 0;
sInt = setInterval(addCharackter, textSpeed)
textFinished = false
}
}
}
I've looked through my code for hours. text is inside part3 and part3 DOES exist, considering it works if I skip the typing process by pressing space. (it also doesn't happen if I were to skip the typing process before part3.)
edit: Another thing that I just realised, line 342 should never be ran because textFinished should equal true (which it is moments before, but when I press space, it magically isn't. I don't change it to false anywhere except in parts that aren't running when the error happens)

Answer 1

Never mind. Found why it wasn't working. Stupid user error.
