I've been registered for adsense for search for years, but when I try and create a new custom search form over at
https://www.google.com/adsense I keep getting javascript errors on the final page where you save your form and get the code.
I've tried IE, FF & Chrome and they all stall at the last hurdle so I don't know what's going on there.
I almost have this working but cannot find anything to do with the extra code mentioned above - my partner-pub number is a plain 16 digit string with no colon and no extension after it.
Maybe they've changed something so I'll have to try again in a couple of days - hopefully I can finish the process then.
