main();
function main(){
var myObject;
//var myCheckSelection = false;
//Make certain that user interaction (display of dialogs, etc.) is turned on.
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.interactWithAll;
if(app.documents.length > 0){
  if(app.selection.length > 0){
   switch(app.selection[0].constructor.name){

    default:
     //Something was selected, but it wasn't a text object, so search the document.
     //myFindChangeByList(app.documents.item(0));
                    //alert("Nothing Selected, Please Select Text Frame or Text.");
   }
  }

  else{
   //Nothing was selected, so simply search the document.
            //myFindChangeByList(app.documents.item(0));
            alert("Nothing Selected, Please Select Text Frame or Text.");
  }
}
else{
