Applescripts Won't Run in CS5

Question

My applescripts, which worked in CS4, do not work in CS5.
Below is the content of one, which counts the characters in an open document. Instead of running, it opens the script editor. When I click on  the green triangle ("start running the scrpt"), it highlights the line that says "var doc = app.documents.everyItem; //Gets list of all open documents" in orange.
//===============================================================
// Name: CharCountOpenDocs
// Description: Counts all open documents in InDesign
// Modification Log
// 100816~aab~Created script from CharCount.jsx
//===============================================================
var k, h; //K is the counter for all of the documents, H counts each document
var doc = app.documents.everyItem; //Gets list of all open documents
var docList = app.documents.length; //Checks to see how many docs are open if 0 closes
if (docList == 0) { //If there are no open documents, shuts down the script
  alert("There are no open documents.");
  exit();
k = 0; //Sets K to zero before we start counting
for (i = 0; docList > i; i++) { //This loops through all of the open documents one at a time
    var myDoc = app.documents.item(i); //Takes each doc in list and works on it one at a time
    h = 0; // Sets document counter to zero.
    for (var j = 0; myDoc.stories.length > j; j++) { //Loops through each story (text chain)
        h = myDoc.stories[j].characters.length + h //Gets character count of each story
    k = k + h; //Adds this document to the main counter
    //alert("You have " + h + " characters in this document" ) //Throws an alert for each document
alert("You have " + k + " characters in all open documents" ) //Throws final alert for all documents

Answer 1

The line that errors:
var doc = app.documents.everyItem; //Gets list of all open documents
Should be:
var doc = app.documents.everyItem(); //Gets list of all open documents
(Note function-invoking parentheses after "everyItem".)
I don't know how that ever worked in CS4 either without the parentheses. You don't need the line anyway, if this is the entire script; that variable is never used.
