I am trying to Set Embedded Data for Multiple Targets on a creative with JavaScript.  I am familiar with setting embedding data into intercepts/surveys by using the simple Embedded Data features on the intercept action sets, to pull in cookie values etc but I have zero understanding of javascript!

Below is a screenshot of the relevant part of my creative.  I have created targets over each of these 3 answers, but would like to set a different embedded data value for each, so I can tell which answer they gave when they arrive at the survey

I have found these directions here, but I’m unsure how to apply them to the creative.  Where do I put the javascript?  And then what do I need to do to pull it to my intercept/survey? 

Thanks in advance for your help!
