Guest Baber
Hello again,

I need to take a sum of 5 text boxes into the 6th one. Can't find a script that do this basic calculation for me or may be due to my less knowledge of  jscript. Can any one help me plz? Here is how the form look like;

[code]
<table width=50% bgcolor="#FFFFFF" cellspacing=1 cellpadding=2>
<tr bgcolor="">      
  <td><b>One</b></td>
  <td><input type="text"></td>
</tr>
<tr bgcolor="">      
  <td><b>Two</b></td>
  <td><input type="text"></td>
</tr>
<tr bgcolor="">      
  <td><b>Three</b></td>
  <td><input type="text"></td>
</tr>
<tr bgcolor="">      
  <td><b>Four</b></td>
  <td><input type="text"></td>
</tr>
<tr bgcolor="">      
  <td><b>Five</b></td>
  <td><input type="text"></td>
</tr>
<tr bgcolor="">      
  <td><b>TOTAL</b></td>
  <td><input type="text"></td>
</tr>

</table>
[/code]
