vimeo tracking code generator not working

got code from https://clicky.com/help/code-generator

and placed after "html body tag" and before "html /body tag" but not working

also confused as the code generator has "https://clicky.com/help/code-generator"

does that mean we don't use vimeo's embed code: iframe src="//player.vimeo.com/video/156343456" width="500" height="375" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen /iframe
