Function updateForm () produces a syntax error I don't understand

Hi -

I am very new to Java Script and am working with some code I found on the inteet that allows me to create a dropdown list in my form based on a list in a spreadsheet. Here is a snippet of code:

[Code]
function updateForm(){
// call your form and coect to the drop-down item
var form = FormApp.openById(1yZ8Y8ZTKpEl78dFSmQd25ng2ouyUPhAP4OCsu4oE2DE);
var namesList = form.getItemById(1967939378).asListItem();
[Code]

The error message I receive is this: Missing ) after argument list. (line 3, file "Code")

I'm stumped!
