                <font face="arial" size="2">Hi Peter,<br /><br />   The only time Javascript "breaks" your search engine viability is when it replaces your content and/or links.  Search engines work by following links, indexing the content on each page, and then following the links on each page.  If your links are replaced by Javascript calls, the search engine won't know what to do.<br />   Since you're just using JS to manipulate numbers within the same page, I can't see this being a problem.  Just make sure that all relevant areas of your site are still linked by traditional means and you should be fine.<br /><br />Cheers,<br /><br />Peter<br /><br /></font>
