Run-time error 91, object variable or With block variable not set

I am new to vb6. I am trying to automatically click a button on a web age. I keep getting the run-time error 91, object variable or With block variable not set. I have also set the HTML object library. Can I get some advice. Here is my code. Thanks

Private Sub WebBrowser1_DocumentComplete(ByVal pDisp As Object, URL As Variant)

Dim doc As HTMLDocument
Set doc = WebBrowser1.Document
doc.All("btnAcknowledge").Click

End Sub

Welcome to the forums! :wave:

How about trying the WebBrowser1_NavigateComplete2 instead?

Or you could use the .Busy property of the Webbrowser...

Code:

---

WebBrowser1.Navigate "www.vbforums.com"
Do While WebBrowser1.Busy = True
        DoEvents
        Sleep 500
    Loop

---

Thanks for your input, however, I used WebBrowser1_NavigateComplete2 and I still receive the same error for the line "doc.All("btnAcknowledge").Click"
