That helped but wasn't quite what I needed to do. However I have worked it out from your suggestion.
First I created a symbol with each bit of info written on a separate layer which I made invisible, I then gave each of those layers a unique name followed by a number. Eg: Pick1, Pick2, Pick3 etc.
var number = Math.floor(Math.random()*(14-1+1)+1);
hypeDocument.getElementById('Pick'+number).style.display = "block";
Finally I had the action run through 'On Symbol Load' within the symbol inspector.
Hope this helps anyone else who may need to do a similar project.
