1120: Access of undefined property [instantiated variable]? (Flex)

Question

I have looked at questions like this, this, this and this, but none of these seem to describe my problem?

I am declaring these variables:

<fx:Script>
    <![CDATA[
        import assets.Page;
        public var oneTwo:Page = new Page("...");
        public var oneThree:Page = new Page("...");
        protected var oneFour:Page = new Page("...");
        protected var oneFive:Page = new Page("...");
        protected var oneSix:Page = new Page("...");

... are referencing objects that do exist, and Flex is okay with the constructors of each of these items. Next, I try to set other properties of these objects:

        oneThree.next = oneFour;
        oneThree.prev = oneTwo;
        oneFour.next = oneFive;
        oneFour.prev = oneThree;
        oneFive.next = oneSix;
        oneFive.prev = oneFour;

etc. Now, when I click each of these, Flex highlights the variable in each instance, and recognizes all of them as valid during coding. But compilation gives:

-1120: Access of undefined property oneThree.
-1120: Access of undefined property oneFour.
-1120: Access of undefined property oneFour.
-1120: Access of undefined property oneFive.

and so on, one for each time each variable is used (so twelve times in the case here). You can see I made some public and some protected, this does not seem to make a difference.

[This][1] question led me to the solution.

The variables in the second code block need to be edited within their own function, getting:

<fx:Script>
    <![CDATA[
        import assets.Page;
        public var oneTwo:Page = new Page("...");
        public var oneThree:Page = new Page("...");
        protected var oneFour:Page = new Page("...");
        protected var oneFive:Page = new Page("...");
        protected var oneSix:Page = new Page("...");

        oneThree.next = oneFour;
        oneThree.prev = oneTwo;
        oneFour.next = oneFive;
        oneFour.prev = oneThree;
        oneFive.next = oneSix;
        oneFive.prev = oneFour;
    ]]>
</fx:Script>

instead of this:

<fx:Script>
    <![CDATA[
        import assets.Page;
        public var oneTwo:Page = new Page("...");
        public var oneThree:Page = new Page("...");
        protected var oneFour:Page = new Page("...");
        protected var oneFive:Page = new Page("...");
        protected var oneSix:Page = new Page("...");

        protected function _init():void
        {
            oneThree.next = oneFour;
            oneThree.prev = oneTwo;
            oneFour.next = oneFive;
            oneFour.prev = oneThree;
            oneFive.next = oneSix;
            oneFive.prev = oneFour;
        }
    ]]>
</fx:Script>

that took care of the errors for me. Hope this helps someone else!!
