I have a span tag
I recon that
won't work since I have to specify class, too, correct?
var string = document.getElementById('v4-25');
document.getElementById('listprice').innerHTML = string;
should print value of 'v4-25' in 'listpirce' ?
H getElementById looks only at the id and since id values must be unique in the page, what you have proposed should work just fine.
