Google maps / Iframe dynamic src element
===

ok so my problem is I have an iframe that is meant to show googlemaps

The src of the iframe will be set to hit googlemaps with an address read from the database being inserted as a location

At the minute the frame is just pure white and no picture appears even, however if the src path is placed into a browser URL it works fine, the test url i have is
"http://maps.google.com/maps/api/staticmap?markers=27+Landseer+Street,+Belfast&size=500x300&sensor=false"

this is valid as you willl see if you put in an address bar.

My aim is to have three frames all named individually and then the src's set on them.
Here is my code so far

VB.NET
    Public Class About
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Session("recentAddressmap1") = ""
        Session("recentAddressmap2") = ""
        Session("recentAddressmap3") = ""
        Session("src1") = ""
        Session("src2") = ""
        Session("src3") = ""
        Dim recentCount As Integer
        recentCount = 0
        Dim addresstest As String = "27 Landseer Street"
        Dim words As String() = addresstest.Split(New Char() {" "c})

        ' Use For Each loop over words and display them
        Dim word As String
        Dim newaddress As String = ""
        Dim loopcounter As Integer = 0
        For Each word In words
            If loopcounter = 0 Then
                newaddress = word
                loopcounter = loopcounter + 1
            Else
                newaddress = newaddress & "+" & word
            End If
        Next
        '''''''''''''''''''''''''''''''''''''''''' DO ENTRY RECENT 1 '''''''''''''''''''''''''''''''''''''''''''''''''''
        Session("recentAddressmap1") = newaddress & ",Belfast"
        Session("src1") = "http://maps.google.com/maps/api/staticmap?markers=" & Session("recentAddressmap1") & "&size=500x300&sensor=false"
        'MsgBox(Session("src1"))
        visualAddress1.Attributes.Add("src", Session("src1"))
    End Sub

End Class
