Hi all,

i cannot debug this code, i suspect it's not pushing the postcodes into the website but it's giving me precious little feedback as to whats wrong - any ideas?

Code: 
Sub Postcode_Distances()

Dim URL As String
Dim count As Integer
Dim waitCounter As Integer
Dim fromCheck As String
Dim toCheck As String
Dim explorerCounter As Integer
Dim resetExplorer As Integer
Dim waitTime As Integer ' seconds


count = 1
distance = 0
prevDistance = 0
prevdistance_direct = 0
waitTime = 2 'seconds
explorerCounter = 0
resetExplorer = 500 'restart explorer after this number of runs
URL = "http://www.freemaptools.com/distance-between-uk-postcodes.htm"


'get to webpage
Set IE = CreateObject("InternetExplorer.Application")
IE.Visible = True
IE.Navigate2 URL
Do While IE.readyState <> 4 Or IE.busy = True
    DoEvents
Loop
        
' Read website information for inputting postcodes
Set form = IE.Document.getElementsByTagName("Form")
Set inputform = form.Item(0)
Set Postcodebox = inputform.Item(0)
Set Postcodebox2 = inputform.Item(1)
Set POSTCODEbutton = inputform.Item(2)
        
Worksheets("Postcodes").Range("A1").Select
Calculate


Do While Range("Postcode_From_Check").Offset(count, 0) <> ""


    fromCheck = Range("Postcode_From_Check").Offset(count, 0).Value
    toCheck = Range("Postcode_To_Check").Offset(count, 0).Value
    manualCheck = Range("Manual_Postcode_Check").Offset(count, 0).Value
    
    If fromCheck = "Invalid" Or toCheck = "Invalid" Or manualCheck = "Invalid" Then
        Range("Distance").Offset(count, 0) = "xxxx"
        Range("Distance_Direct").Offset(count, 0) = "xxxx"
    ElseIf Range("Distance").Offset(count, 0) = "" Then
        ' Read 'from' postcode - if valid use given postcode, otherwise use corrected version
        Range("Distance").Offset(count, 0).Select
        If fromCheck = "Valid" Then
            StartLocation = Range("Postcode_From").Offset(count, 0).Value
        Else
            StartLocation = fromCheck
        End If

Sounds to me that it might be that the page has changed.

Can't test your code right now but I may try it later.

i think im having problems with objects not being defined .

I stripped it back and did a small test on the below and it worked, is the below what you expect the webpage to do?

reference for Microsoft Internet Controls needs to be added first.

Code: 
Sub test()
'tools > references > Microsoft Interent Controls
Dim IE As New InternetExplorer
Dim inpt As Object, ieObj As Object, ieBtn As Object, btn As Object




IE.Visible = True
IE.Navigate "http://www.freemaptools.com/distance-between-uk-postcodes.htm"
Do While IE.ReadyState <> 4 Or IE.Busy = True
    DoEvents
Loop


Set inpt = IE.Document.getelementsbytagname("Input")


StartLocation = "Cr3 0BF"
EndLocation = "CR3 0EA"


For Each ieObj In inpt
If ieObj.Name = "pointa" Then ieObj.Value = StartLocation
If ieObj.Name = "pointb" Then ieObj.Value = EndLocation
Next
Set btn = IE.Document.getelementsbyclassname("fmtbutton")


For Each ieBtn In btn
If ieBtn.innertext = " Show " Then
ieBtn.Click
Exit For
End If
Next
'IE.Quit
End Sub

yeah - the input is the 2 postcodes and the output is the 2x distances from the page which are then pasted in the xls

the above code works but i'm not sure how to integrate into mine - is it a case of replacing all of the object definitions to match yours?

With your original code is there no interaction with the site at all?

This is a long shot.

Try changing this,
Code: 
Set inputform = form.Item(0)
to this.
Code: 
Set inputform = form.Item(1)

this caused the 'from postcode' to be entered in the 'to postcode' box on the site. So identifies the problem as being located in the structure of the new site

Well that sounds as though you've at least got the correct form.

What you'll need to do next is adjust this code so Postcodebox, Postcodebox2 etc. point to the correct fields in the form.
Code: 
Set Postcodebox = inputform.Item(0)
Set Postcodebox2 = inputform.Item(1)
Set POSTCODEbutton = inputform.Item(2)

Start by trying this.
Code: 
Set postcodebox = inputform("pointa")
Set postcodebox2 = inputform("pointb")
