here's the code:

//Variable storing when the platform is android var android = (Ti.Platform.name == "android");

//BG Color to White //Titanium.UI.setBackgroundColor(android?#181818;

//Create 5 individual windows var win1 = Ti.UI.createWindow();

//Create the table view and set the data var tableview = Titanium.UI.createTableView({top:50});
win1.add(tableview);

//Set data counter to keep track of getData calls var dataCount = 0;
var epicFail = false;
//Make client var xhr = Ti.Network.createHTTPClient();

//This function loads the game data function getData(window, platform) {

//Data failure
xhr.onerror = function (e) { 
    if (!epicFail) { 
        alert("A Net Load failed! Best to check your connection and reload app later!"); 
    } 
    epicFail = true; 
};
//Upon data load
xhr.onload = function( ) {
    //Create clean data array
    var data = [];        
    //Get the JSON out
    var resp = eval("(" + this.responseText + ")");

    //Set img width, if DS, make it bigger
    var imgWidth = 50;
    if (platform == "Nintendo%20DS") {
        imgWidth = 75;
    }

    Ti.API.info('PRODUCT COUNT = ' + resp.products.length);

    //Loop through and create rows for every product pulled
    for (var i=0;i < resp.products.length;i++) {
        var row = Ti.UI.createTableViewRow({
