Remove Children Of a Different Class As3 - actionscript-3

Question

I have added many objects to the stage (in the Achievements.as class) to create an achievements board. I want to remove all of the children from the main.as class when someone presses a back button is there a way of doing this. Also, is there a way of creating a custom textField class where each textField.selectable = false without having to assign it to each one individually.
public static var texts:Vector.<TextField> = new Vector.<TextField>();
public static var titleTxt:Vector.<TextField> = new Vector.<TextField>();
public static var descripTxt:Vector.<TextField> = new Vector.<TextField>();
public static var rewardTxt:Vector.<TextField> = new Vector.<TextField>();
public static var achCoins:Vector.<MovieClip> = new Vector.<MovieClip>();
for (var j:int = 0; j < 30; j++)
{
achCoins[j].x = 240;
achCoins[j].y = 45 + j * 70;
addChild(achCoins[j]);
descripTxt[j].x = 0;
descripTxt[j].y = 30 + 70 * j;
//descripTxt[j].antiAliasType = AntiAliasType.ADVANCED;
descripTxt[j].defaultTextFormat = tf2;
descripTxt[j].text = descriptext[j];
descripTxt[j].embedFonts = true;
addChild(descripTxt[j]);
titleTxt[j].x = 0;
titleTxt[j].y = j * 70;
//titleTxt[j].antiAliasType = AntiAliasType.ADVANCED;
titleTxt[j].defaultTextFormat = tf3;
titleTxt[j].text = titletext[j];
titleTxt[j].embedFonts = true;
addChild(titleTxt[j]);
rewardTxt[j].x = 200;
rewardTxt[j].y = 30 + j * 70;
rewardTxt[j].text = reward[j].toString();
rewardTxt[j].setTextFormat(tf1);
rewardTxt[j].embedFonts = true;
rewardTxt[j].textColor = 0x000000;
addChild(rewardTxt[j]);
texts[j].text = Main.achievement[j] + "/" + totnum[j];
texts[j].setTextFormat(tf1);
texts[j].x = 200;
texts[j].y = j * 70;
texts[j].embedFonts = true;
addChild(texts[j]);
}
I then remove the children using this code
for (var k:int = 0; k < 30; k++)
{
removeChild(achievementback.descripTxt[k]);
removeChild(achievementback.titleTxt[k]);
removeChild(achievementback.rewardTxt[k]);
removeChild(achievementback.texts[k]);
}
I get the error
1119: Access of possibly undefined property descripTxt through a
reference with static type Achievements.
for (var i:int = 0; i < 30; i++)
{
texts.push(new TextField());
titleTxt.push(new TextField());
rewardTxt.push(new TextField());
descripTxt.push(new TextField());
achCoins.push(new coinSmall());
{
In Achievements.as Class
public function RemoveTextboxes(){
for (var k:int = 0; k < 30; k++)
{
removeChild(descripTxt[k]);
removeChild(titleTxt[k]);
removeChild(rewardTxt[k]);
removeChild(texts[k]);
}
}
In Main.as Class
achievementback.RemoveTextBoxes()
Here is my whole achievements class

removeChild(titleTxt[k]);
removeChild(rewardTxt[k]);
removeChild(texts[k]);
}
}}
}
The arrays descriptext:Array acharr:Array titletext:Array All have the correct content in them but it is a lot of text so I took it out to post this
Here is the code I am using to remove the children from Main.as
function achievementExit():void
{
removeChild(back1);
removeChild(coin_sm);
removeChild(coinAmt);
removeChild(completed);
removeChild(achTit);
removeChild(achback);
achievementback.RemoveTextBoxes()
removeChild(achievementback)
removeChild(scrollPane);
}

Answer 1

I had to slightly modify the code and comment out where you set the text in the boxes to get this to run (since I'm missing some code) But What seemed to be my issue is that the textboxes were getting removed but your green shape was staying on the stage. Added a vector to hold all those and added those to the remove function.

removeChild(texts[k]);
removeChild(graphix[k]);
}
}
}
}
I also had to change your custom classes back to MovieClip and TextBox since I didnt have source for those.

Answer 2

It should be:
for (var k:int = 0; k < 30; k++)
{
achievementback.removeChild(achievementback.descripTxt[k]);
achievementback.removeChild(achievementback.titleTxt[k]);
achievementback.removeChild(achievementback.rewardTxt[k]);
achievementback.removeChild(achievementback.texts[k]);
}
Update
Are you even adding those DisplayObjects to your vector arrays?
