Weather service not working anymore?

Hi
I'm doing it like that

Code:

require('socket.http')

forecast = {}

function parsetag(parser, tag, attributes)
 if tag == 'time' then
   table.insert(forecast, {})
 elseif tag == 'symbol' then
   forecast[ #forecast ].symbol = attributes.name
 elseif tag == 'precipitation' then
   forecast[ #forecast ].precipitation = attributes.value
 elseif tag == 'windDirection' then
   forecast[ #forecast ].wind_direction = attributes.code
 elseif tag == 'windSpeed' then
   forecast[ #forecast ].wind_speed = attributes.mps
 elseif tag == 'temperature' then
   forecast[ #forecast ].temperature = attributes.value
 elseif tag == 'pressure' then
   forecast[ #forecast ].pressure = attributes.value
 end
end

url = 'http://www.yr.no/place/United_Kingdom/England/Farnborough/varsel.xml'
data, err = socket.http.request(url)

if data then
 require('lxp').new({
   StartElement = parsetag
 }):parse(data)


 grp.update('Weather precipitation', tonumber(forecast[1].precipitation))
 grp.update('Weather symbol', forecast[1].symbol)
 grp.update('Weather windDirection', forecast[1].wind_direction)
 grp.update('Weather windSpeed', tonumber(forecast[1].wind_speed))
 grp.update('Weather temperature', tonumber(forecast[1].temperature))
 grp.update('Weather pressure', tonumber(forecast[1].pressure))

 --log(forecast)
 
else
 alert('Fetch failed: ' .. tostring(err))
end

Looks great, but i still dont understand where to put the GA in. Sorry for the low lewel of knowlegde.
