ผมแยก Function ไว้อะครับ
Function ต่อจาก ChkUser ก็เป็น Function Validate form ทั่วไปอะครับ
อีกอันก็เป็น Form ทั่วไปที่ใช้ call function นี้อะครับ
ส่วนหน้าที่อยากให้ไปต่อหลังจาก check username แล้วก็เป็นหน้าคำสั้ง sql ลง Base อะครับ

คุณลองไล่ alert('Debug'); ตรง function ที่มีปัญหาครับ ว่ามันหลุดตรงไหน และก็อย่าลืมใส่ return true; ในบรรทัดสุดท้ายด้วยครับ
