I added message box

I simplified code to:

Private Sub Form_Current()
Dim Newasin
Newasin = [AMAZONDEALSF2].[Form]![ASIN]
    WebBrowser5.Navigate "http://www.amazon.co.uk/dp/" & Newasin
    MsgBox "http://www.amazon.co.uk/dp/" & Newasin
End Sub

Let me explain this again.
1. I have subform a field is ASIN it is a continuous form
[AMAZONDEALSF2]
2. I have a form on the form is field asin its control is:
=[AMAZONDEALSF2].[Form]![ASIN]
3. If I click from one record to another on the subform the field asin IN THE FORM updates.
On start the webbrowser loads the first page and give the message box
4. If I click from one record to another on the subform the webbrowser does not update and no message box either. The browser is not refreshing
5. I tried adding this code to the webbrowser
Private Sub WebBrowser5_Updated(Code As Integer)
Dim Newasin
Newasin = [AMAZONDEALSF2].[Form]![ASIN]
    WebBrowser5.Navigate "http://www.amazon.co.uk/dp/" & Newasin
    MsgBox "http://www.amazon.co.uk/dp/" & Newasin
End Sub

It gives 2 message boxes then stops but both for the first asin. Clicking down the subform still refreshes asin on the form but not the browser.

My VBA is totally limited. The issue seems to be that clicking down the subform refreshes asin on the form but not the browser.

See this Tip
FORM
=Forms!FormName!FieldName
SUBFORM
=Forms!ParentForm!SubForm.Form!FieldName

You'd need to tell the parent to update when the sub forms Current event fires.
