I have to admit, the missing ) is a typo. I made up the ice cream example to try to simplify my problem, and accidentally missed it off.
Perhaps my example is too simple. > I have a small form on a page that is mostly optional fields with the > exception of some drop down boxes. My actual form has 3 optional fields, and this complicated matters with matching URLs. Fortunately, two of the fields are limits for a price search, so I've used "-" to identify the re, and the third is a text description so I'm expecting URLs that look like "/100-200/persian %20rug/" (Where 100-200 is the price range, and "persian%20rug" is a quoted text search). My issue is that any of those 3 fields may not be submitted, but somehow I need to redirect to the process view. The <a href="http://jobs.guardian.co.uk/jobs/"; title="Guardian Jobs">Guardian Jobs</a> site is a nice example of the effect I want to create as you add filtering paramters on the left, although I'm using a form to collect user input as opposed to giving them a list of ranges which is more difficult. I hope that clears a few things up.
