InDesign Error for FindChangeByList Script (which I slightly customized)

Hi,

I'm new to scripting, but I don't understand how this error could come from my customization because it refers to a line that I did not edit. This is basically identical to the built-in script called FindChangeByList found in the Scripts Panel under Application > Samples > JavaScript. The only thing I changed was the location of the file that contains the FindChange List. I'll paste the script below and highlight the portion that the error is referring to.

 main();

var myObject;
//Make certain that user interaction (display of dialogs, etc.) is turned on.

myFindChangeByList(app.documents.item(0));
