ClickBank ID Inserter

Hello RAC coders, I have a site where I offer my affiliate marketing material to help them sell my products 4 ClickBank. I what a simple bit of JaveScript that asks the user for their ClickBank ID, via a prompt box, and then have the script replace all instance of NICKNAME with ClickBank ID. For example [[login to view URL]][1] would have NICKNAME replace with ClickBank ID I would want the code to replace NICKNAME for all products on the site. Should not ba a problem as NICKNAME (uppercase) would be the unique identifier. See: <[login to view URL]> a site that is doing something similar. NOTE, I want the done in Javascript. Also, though I am skilled on internet I may need a little coaching to insert code in Net objects (Website design program). Regards Jeff
