You first need to ascertain the ID or unique about the HTML elements you want to interact with. You can do this by inspecting the webpage (or viewing the page source but that isn't as interactive as the inspect option)
Once you have those, here we have the ID "combinations959" to enter the number into and then use the href property of the anchor HTML element to find it to click on.
If it were me I'd install SeleniumBASIC 2.0.9,
https://github.com/florentbr/seleniumbasic/releases, install it, then download the web driver that matches the browser in use. IE is a bit of a problem here as it involves more setup (I haven't tried it) here is what using chrome would look like.
I'd go here
Microsoft Edge WebDriver | Microsoft Edge Developer download the stable x64 file. Once downloaded, you take the msedgedriver.exe file from the zip and place it on the SeleniumBASIC folder at C:\Users\your user name\AppData\Local\SeleniumBASIC, rename it edgedriver.exe.
In the VBA Editor, click tools references and select SeleniumBasic Type Library.
The code would look something like
Private Sub btnEdgeBrowser_Click()
Dim eDriver As EdgeDriver
Dim inputField As WebElement
Dim paragraphElement As WebElement
Dim codeRan As Boolean
codeRan = False
Set eDriver = New EdgeDriver
eDriver.Get "https://risultatilotto.com/superenalotto/generatore-numeri/?fbclid=IwY2xjawJ5Z2hleHRuA2FlbQIxMQABHs11Hnek _
5nY9F1AETH0c0GlwvbgmO7lBtLksJWj6jWLeIi2JEs9r4P6XTgWA_aem_-GZ_Jp-KmiRJiprneGOzvw"
eDriver.Wait 2000 ' wait 2 seconds for it respond
On Error GoTo exitTheCode
' find the inputbox, they change the name of it
' get all the paragraphs and find the text Combinations:, take that paragraph and grab the inputbox in it
For Each paragraphElement In eDriver.FindElementsByTag("p")
If paragraphElement.Text = "Combinations: " Then
Set inputField = paragraphElement.FindElementByTag("Input")
Exit For
End If
Next
If Not inputField Is Nothing Then
' the correct inputbox was found, enter the required number
inputField.Clear
inputField.SendKeys "6"
Set inputField = Nothing
End If
' to find the XPATH, right click the element in the inspect area and select Copy XPath
' click the anchor to proceed
eDriver.FindElementByXPath("//*[@id='single-blocks']/div/div/div[1]/div/div/div/div[2]/div/a").Click
eDriver.Wait 2000
codeRan = True
exitTheCode:
If Not codeRan Then
MsgBox "There was an issue attempting to automate the page. " & vbCrLf & Error(Err), vbCritical, "Process Failed"
End If
On Error Resume Next
eDriver.Close
Set eDriver = Nothing
End Sub
