Could someone please tell me what's wrong with the below script? I need it to use the FindChangeList to do some basic formatting (replacing double-dashes with em-dashes), then apply the next style, then find my last two lines and format them to a paragraph style, THEN map styles to tags. It's all working EXCEPT it does not do the initial "find/replace" formatting. I suspect it's a conflict of the FindChangeList somehow?? Any and all help is appreciated.

//FindChangeByList.jsx
main();
function main(){
	var myObject;
	var myCheckSelection = false;
	if(app.documents.length > 0){
		if(app.selection.length > 0){
			switch(app.selection[0].constructor.name){
				case "InsertionPoint":
				case "Character":
				case "Word":
				case "TextStyleRange":
				case "Line":
				case "Paragraph":
				case "TextColumn":
				case "Text":
					myObject = myDisplayDialog();
					myCheckSelection = myObject[1];
					myObject = myObject[0];
					if(myObject != "None"){
						myFindChangeByList(myObject, myCheckSelection);
					}
					break;
				default:
					myFindChangeByList(app.documents.item(0), false);
			}
		}
		else{
			//Nothing was selected, so simply search the document.
			myFindChangeByList(app.documents.item(0), false);
		}
	}
	else{
		alert("No documents are open. Please open a document and try again.");
	}
}

	var myObject;
	var myDialog = app.dialogs.add({name:"FindChangeByList"});
