local variable in Flash Builder 4.5

Question

I have two scripts in a View, one script is inside a Component. In the Component script I need to add numbers from data as they are added to a list and then display the total in a label placed in the View. If I declare the variable in the first script, the Component script can't see it and if I declare it in the Component Script the label can't see it. How will I declare it so that everyone in the view can see it? Thanks, Kim

Here is the code, the problem is where should I place the var MyTotal so it can be used anywhere in the view:

<s:view
     <fx:Script>
          <![CDATA[
                  //if I place it here the next CDATA inside IconItemRender can't see it.
                  private static var MyTotal:Number=0;
          ]]>
     </fx:Script>
     <fx:Declarations>
          <s:CurrencyFormatter id="usdFormatter" useCurrencySymbol="true"/>
     </fx:Declarations>
        <s:itemRenderer>
           <fx:Component>
               <s:IconItemRender ..............>
                  <fx:Script>
                     <![CDATA[
                              //if I place it here the Label "TotalAmountLb" can't see it.
                             // and it get reset to 0 everytime I call the function getInvoiceAmount.
                             private static var MyTotal:Number=0;

                             private function getInvoiceAmount(item:Object):String
                             {
                               MyTotal = MyTotal + Number(item.Amount);     
                             }
                    ]]>
                  </fx:Script>
               </s:IconItemRenderer>
            </fx:Component>
         </s:itemRenderer>
      </s:List>
      <s:Label id="TotalAmountLb" text="{usdFormatter.format(MyTotal)}"/>
  </s:view>

I think your question doesn't make any sense. first make your question clear. — Exhausted, Nov 20 '11 at 09:48
if i understand this right, you should give a id for your component. With an id, you can refer variables inside component. Other way is the dispatch custom event from component to view. — Jarno Lahtinen, Nov 20 '11 at 18:47
I tried to give the Component the id "MyId" and then added MyId.MyTotal. Then I get an error 1119 — Kim HJ, Nov 21 '11 at 02:33

Just try this:
Declare MyTotal in first script.
And in component script just try to access with outerDocument.MyTotal

No, I get an error saying: 1178: Attempted access to inaccessible property MyTotal through a reference with static type views – Kim HJ Nov 25 '11 at 00:19
@KimHJ think you have to declare `MyTotal` to `public` or `protected` – Santhosh Nayak Nov 25 '11 at 04:15

Found the solution, I had to add [Bindable] before the declaration.
