I need some help created a google weather api using vb .net.

I found the code online and there are no errors. Problem is that I can't seem to display wether information. Nothing shows up on screen and I am not sure what I did wrong. any ideas?

Imports System.Net

Partial Class UI_MasterPage
    Inherits System.Web.UI.MasterPage

    Protected Sub SearchIB_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles SearchIB.Click
        Dim WeatherData As New Weather.WeatherInfo_Typed
        WeatherData = Weather.Grab_Weather("texas")
        temp.InnerHtml &= WeatherData.location & "--" & WeatherData.forcast_date & "--" & WeatherData.checked_time_date & "--" & WeatherData.humidity & "--" & WeatherData.forcast_date 
    End Sub
End Class
