Problem with DHTMLX Desinger Code

I started with my first app:
-Designed a layout in the desinger
-Copy the code in the html file

I worked with the tutorial: docs.dhtmlx.com/doku.php?id=visu … ner_to_app

But the Browser return the error message:
dhtmlx is not defined -> dhtmlx.image_path=’./codebase/imgs/’;

Why???

Code:

/*these styles allows dhtmlxLayout to work in the Full Screen mode in different browsers correctly*/ html, body { width: 100%; height: 100%; margin: 0px; overflow: hidden; background-color:white; }
<script type="text/javascript">
  window.onload = function(){
    dhtmlx.image_path='codebase/imgs/';

var main_layout = new dhtmlXLayoutObject(document.body, '2U');


}

It seems that dhtmlx.js was not loaded.
Please check that

points to valid file.

But when i comment out the line it knows the dhtmlXLayoutObject.

You are using dhtmlx 3.0, right?

Right… and i’m a beginner :wink:

Can you zip your demo app, and attach to the post
I have double-checked code - and still don’t see how dhtmlx can be not defined, and layout works in the same time.

Sorry I worked with a older dhtmlx version… It works now.

Thanks
