Where did u add the script exactly?, in aspx file or as a seperate JS file or injected/registered via code behind?..did u check whether the script is being rendered to the client?..did u hook it to an event(s) properly?..if its in a JS file then did u add reference to it in aspx?

I really dont expect u to answer these to me...if something is wrong with scripts then I ask these questions to myself :)

U could check whether its rendering or not on page requests by using developer tool (if u r using IE/Chrome)/firebug (if u r using Firefox)
