3. Copy and paste the shortcode, such as [Wow-Modal-Window id=1] to where you want the modal window to appear.
I am not sure what you mean by where you want to modal to appear. I want the modal window to pop up on my screen when I click the side menumselection button icon. Where do I put the link for the modal window in this case? Do I put it in the side menu Modal Window Id box? and how do I format it. Do I need the square brackets? Right now I have the modal window id as: [Wow-Modal-Windows id=1] but the modal window does not show up when I click the button on the side menu.

This is what I have in my side menu setup. I am trying to open the modal window as indicated the modal windows ID is shown in the following screenshot.

So how do I get this to work because right now when I click the button for Contacts nothing happens.
Insert in option Modal Window Id – wow-modal-id-2
Insert shortcode [Wow-Modal-Windows id=2] in a page content, where you want the modal window to appear.
