Just a simple update of this great contribution for OSC Milestone-2. Places an update button in the estimate box rather than text to refresh the page with the estimates showing. Removed the weight listing at the top in case you use a package tare weight which would cause 2 different weights to show in the same estimate. Removed the warning for if you are not logged in as it should not matter since it is just an estimate that is available to all users on the site. Now leaves the zip code field blank rather than auto-inserting the store's zip, as most customers need an estimate for their own zip code and not the store's zip.
