Excel 2010 Select IE Dropdown

Not much so far, I'm stuck on this point...

Sub PullData()
' Comment out the below line to stop pop-up box!
' MsgBox ("Be patient, the script will run after you click ok.")
' Reference MS Internet Controls

' Declare variables
    Dim IE As InternetExplorer
    Set IE = New InternetExplorer
    
' Navigate to correct page
    With IE
        .Visible = True
        .Navigate "website here"
    End With
' Wait for page to load - allows server to fail
    Application.Wait (Now + TimeValue("00:00:03"))
' Fill in the search form
    With IE
        .Document.form1   <<<stuck here
    End With

    With IE
        '.Quit
    End With
    
    Set IE = Nothing
End Sub

EDIT:
Might be important to mention that the table output one the button is pressed will always be a different size
