Wow, that's so far off I'm not even sure where to start. Marked OT 
because this has more to do with a fundamental misunderstanding of how 
webapps work than anything struts-ish.

JavaScript is run client-side, Struts tags (or any other, for that 
matter) are run server-side. This sounds familiar; did we have a go at 
this once before?

You _could_ do something like (syntax probably wrong; working with other 
technology today):

var total = <c:out value='${total.intValue}'/>;
total += whatever;

and then reference 'total' with a javascript chunk or via any number of 
element replacement techniques on the page.

Does that help?
