Lab 2 : Syntax error

1. Missing a semicolon

     สาเหตุ ลืมใส่สัญลักษณ์ semicolon (;) ด้านหลังคำสั่ง

     วิธีแก้ ใส่ semicolon (;) ตรงที่มีแจ้งเตือนแถบสีเหลือง

2. The variable "..." does not exist

     สาเหตุ ใส่ชื่อตัวแปรไม่ตรงตามที่เราได้กำหนดไว้

                ประกาศตัวแปรแบบ local ทำให้ฟังก์ชันที่ต้องใช้ค่าตัวแปรหาค่าตัวแปรไม่เจอ

     วิธีแก้ แก้ไขชื่อตัวแปรให้ตรงกัน

              แก้ไขการประกาศตัวแปรเป็นแบบ global

3. The function "..." does not exist 

     สาเหตุ ใส่ชื่อฟังก์ชันไม่ตรงตามชื่อฟังก์ชันของ System function

     วิธีแก้ แก้ไขชื่อฟังก์ชันให้ถูกต้อง
