主题：if语句问题

dim dt as date

if e.form.controls("radiobutton1") .checked = true

   dt = date.today()

        else if e.form.controls("radiobutton2") .checked = true

   dt = date.today.adddays(1)

        else e.form.controls("radiobutton3") .checked = true

   dt = date.today.adddays(2)

end if

点击radiobutton3, 没有获取到dt的值，哪里不对呢？
