Well, probably the simplest method would be to create an empty element on
the page to contain the percentage info ­ I don¹t know your page structure
so I¹ll leave it to you to decide what the most semantic choice of element
is. You¹ll need to give it an ID, so if you require more than one, append an
incrementing number to the ID name (eg, id-name1, id-name2 etc).

The JS would need to contain a line like so:

document.getElementById(³id-name1²).innerHTML = ³30%²;

I can elaborate further with a complete script example if you need it.
