Creation of HTML page Problems

Creation of HTML page Problems

Hello,
1) I have a problem. when I try to create an HTML page, screen becomes gray and nothing is clickable. I have to reload the page.
2) at link  https://www.zoho.com/creator/help/views/create-html-page.html i read: " 6. You can create your view based on a template by selecting the  Choose Template  button". where is this button?
thanks a lot
