Need help in OnChange event Javascript
<p>I have five text fields which are mark1, mark2, mark3, mark4 and total. I have a problem to make the total automatically display in the text field. I have no problem with the calculation part. But I can't make the total to be display automatically in the text field. How can I make the total to be automatically display in the textfield once the user have finish entered all the four marks? I know it have to do with the OnChange event using Javascript. But I did not get the right codes. Does anyone can help me with this? Really need your advise.</p>

<p>Thank you.</p>
