Hi Linda
I'm not familiar with the website builder you're using but here are some general instructions on how you would do this.
You will need to unzip the deployment zip and upload the folder and its contents to your website. You can then use the same embed code that you have been using but change the url in it to match where you have uploaded the folder.
e.g.
<iframe src="
www.yourwebsitename.co.uk/xerte_project/index.html
" width="802" height="602" frameborder="0" style="float:left; position:relative; top:0px; left:0px; z-index:0;">
