The obvious question is: how is your script to know the value of the string from one call on the page to the next?

The most straightforward method would be a hidden field in the form containing the value of the string as it stands at present. Of course, if the string gets big, this could get to be a tedious load on the browser. If that's the case, then some sort of sessioning will be in order.
