ผมต้องแทรกไปตรงใหนอะครับ เพราะในส่วนที่ให้มันคำนวนผลลัพธ์ ของผมมันเป็นแบบนี้อะCode (PHP) <script>
function calcfunc() {
var a1 = document.form1.a1.value.split(',').join('');
var a2 = document.form1.a2.value.split(',').join('');
var a4 = document.form1.a4.value.split(',').join('');
var a5 = document.form1.a5.value.split(',').join('');
var val1 = parseFloat(a1);
var val2 = parseFloat(a2);
var val4 = parseFloat(a4);
var val5 = parseFloat(a5);
//ส่วนที่แสดงผลลัพธ์
document.form1.a3.value=val1+val2;
document.form1.a6.value=val4+val5;
}
</script>
