ก็ คำสั่ง เลือกคณะ ของน้องเป็นแบบนี้
<select id="Faculty" name="Faculty" onChange = "ListFaculty(this.value)">
คำสั่งคือ ใช้ onChange(เมื่อเปลี่ยน) ให้เรียกฟังชัน ListFaculty ซึ่งฟังชันดังกล่าว ไม่มีอยู่ใน โค้ดของน้องครับ

ก็ให้สังเกตุว่า แต่ละ dropdown เรียกฟังชันอะไร แล้วก็ให้ไปดูว่าฟังชันทำอะไรบ้างครับ
