<script type="text/javascript">
function CalculateTotal(){

var k=document.percent.total_paid.value;
var total=(p/k);
var gtotal=total*100;
//var lll=<?php //echo $gtotal; ?>;

<form id="percent" name="percent">
<td>Government share capital out of total paid up share capital</td>
<td><input type="text" name="govt_share_capital" id="govt_share_capital" /></td>
<td>Total Paid up share capital</td>
<td><input type="text" name="total_paid" id="total_paid" /></td>
<td>Percentage of Government share capital to total paid up share capital</td>
<input type="text" name="gtotal" id="gtotal" value="<?php echo $lll; ?>" onclick="javascript:CalculateTotal();"/>
<?php $total = "<script language=javascript>document.write(gtotal);</script>";
echo $total; ?>
