Why this script unfunction?

Question

Hi everyone
I try joint to scripts togeter:
//======================================================================================== ===
function main() {
    // Your settings
var myDocuments = app.documents.everyItem();
var myLayers = myDocuments.layers.everyItem();
//Locked text frames on master spreads are not touched.
//If you want to unlock them you have to add something like this:
//Unlock ALL page items in every document on spreads and master spreads (optional):
myDocuments.pageItems.everyItem().locked = false;
var myPageItemsOnNormalSpreads = myDocuments.spreads.everyItem().pageItems.everyItem();
//Unlock the layers (optional)
myLayers.locked = false;
//Lock all first level page items on normal spreads
//That leaves the page items on master spreads unlocked:
myPageItemsOnNormalSpreads.locked = true;
    var searchList = [
        [ "USA" , "Obama" ],
        [ "rocket" , "sky" ],
        [ "New York" , "Los Angeles" ]
    app.findChangeGrepOptions.includeMasterPages = true;
    app.findGrepPreferences = app.changeGrepPreferences = null;
var myTarget = myDocuments.findGrep();
//Flattening the myTarget array:
var flattenedFoundArray = [];
for(var n=0;n<myTarget.length;n++){
    flattenedFoundArray = flattenedFoundArray.concat(myTarget[n]);
for(var n=flattenedFoundArray.length-1;n>=0;n--){
    flattenedFoundArray[n].contents = searchList;
    for ( var j = 0; j < searchList.length; j++ ) {
        var curSearch = searchList[j];
        app.findGrepPreferences.findWhat = curSearch[0];
        app.changeGrepPreferences.changeTo= curSearch[1];
        target.changeGrep();
//Unlock all objects on normal spreads:
myPageItemsOnNormalSpreads.locked = false;
    app.findGrepPreferences = app.changeGrepPreferences = null;
} // main
//======================================================================================== ===
