Quick Javacode modifcation

This is a quick and easy code modification. I have a page that has a countdown timer on it, when the timer ends currently there is just a simple message that comes up that says "the timer has ended" I need a coder who can modify this code so that when the countdown time ends, and error message appears that says "The time on this offer has expired, you will need to start over" and then when they hit "Okay" it takes them to a new page that I can specify. This should be a pretty simple job. I'll send the winning coder the page HTML to modify, the coder should ONLY modify the JavaScript part of it. Thanks ## Deliverables Coder will be giving the page URL with the javacode on it, after selection has taken place.
