  Sub NavigateWebForms()
    ' Set references for Internet Explorer and HTML document
    Dim IE As Object
    Dim HTMLDoc As Object
    Dim formElement As Object

    ' Create a new instance of Internet Explorer
    Set IE = CreateObject("InternetExplorer.Application")

    ' Define the URL of the webpage with the form
    Dim url As String
    url = "https://www.msexcelvba.com"

    ' Navigate to the webpage
    IE.Navigate url

    ' Wait for the webpage to load
    Do While IE.Busy Or IE.ReadyState <> 4
        Application.Wait DateAdd("s", 1, Now)
    Loop

    ' Get the HTML document
    Set HTMLDoc = IE.Document

    ' Locate the form by its name or index (adjust as needed)
    ' Example: Locate form by name
    Set formElement = HTMLDoc.Forms("exampleFormName")

    ' Check if the form is found before interacting with it
    If Not formElement Is Nothing Then
        ' Interact with form elements (adjust as needed)
        ' Example: Input data into a text field
        formElement.elements("textFieldName").Value = "YourData"

        ' Additional interactions can be added based on form elements

        ' Submit the form (adjust as needed)
        ' Example: Click the submit button
        formElement.submit
    Else
        MsgBox "Form not found."
