The template uses AJAX to load pages. In order to allow Chrome to execute scripts locally you’ll need to append the following string to your shortcut.

-allow-file-access-from-files

Firefox falls back to Flash to play those files. You’d need to change your sandbox settings or test it on a webserver like MAMP. It will run fine online, though.

The form is a very simple script that does not support multiple instances. This means it’s unique and cannot work along other forms. You can add as many fields you like, but you need to adapt the php processor and also the net.flashedge.app javascript.

In the js file, around line 699 you’ll find the following:

$.ajax({
 type: "POST", url: path, data: "name=" + name + "&email=" + email + "&message=" + message, dataType: "html",

Add your custom fields to that line, like this:

$.ajax({
type: "POST", url: path, data: "name=" + name + "&email=" + email + "&message=" + message, + "&phone=" + phone, dataType: "html",

Once you edited it, minify the js file and add a min suffix like the existing one. Keep sure you have the new fields parsed also in the php file by adding them in the code.
