             dim theform
             set theform = document.form1
             ' Return the value from the first drop-down menu. Drop-down text
             ' boxes return values as text. The Cint function converts text
             ' into an integer.
             firstvalue = Cint(theform.drop1.options _
             ' Return the value from the second drop-down menu.
             secondvalue = Cint(theform.drop2.options _
             ' Display the results in a text box.
             theform.Text1.value = firstvalue + secondvalue
           end sub
