Please note: You will need to contact your account manager to activate this feature before using it.
You will need to use either
the hyperlink interactivity element and put in the following code:
javascript:ShowPopupVimeo([Width],[Height],[VideoID]);
The 3 parameters in the above example need to be changed to suit the needs of the video pop up. The width and height values are in pixels. The video id can be grabbed from the link of the video.
Or you may use the html overlay if you wish to put an image on the page, and just put in an <a href="javascript:ShowPopupVimeo([Width],[Height],[VideoID]);"><img></a> so that the image calls that function.
