location in the form on http://weather.yahoo.com/ - currently where it says 
'Enter city of zip code'. 

The WOEID numerical id will be in the URL of the page you get redirected to 
after submitting the form e.g. in the URL 
http://weather.yahoo.com/united-kingdom/england/newcastle-upon-tyne-30079/ the
