Ok, with my limited hacking skills, this is what I came up with. In your dtregister.php look around line 3939 to 4066, compare and make the changes.
<table>
<tr><td colspan=\"2\"><hr></td></tr>
<tr><td colspan=\"2\" ><strong><?php echo DT_ADDITIONAL_INFORMATION;?></strong></td>
<?php
/*
for($i=0;$i<$n;$i++)
{
$rowCustom=$rowCustoms[$i];
?>
<tr><td><?php echo $rowCustom->label?>:</td><td><input type=\"text\" class=\"inputbox\" name=\"<?php echo $rowCustom->name?>\" size=\"<?php echo $rowCustom->field_size?>\"></td></tr>
<?php
}
*/
for($i=0,$n=count($rowCustoms);$i<$n;$i++)
{
$rowCustom=$rowCustoms[$i];
if($_SESSION[\'register\'][\'reg_type\'] == \'reg_individual\'){
}else{
if($rowCustom->group_behave==\'1\'){
continue;
}
}
?>
<tr>
<td width=\"100%\" align=\"left\" valign=\"top\">
<strong><?php echo stripslashes($rowCustom->label); ?>:
</strong>
<?php if($rowCustom->required){echo \"<span class=\'required\'>[code]<table>
<tr><td colspan=\"2\"><hr></td></tr>
<tr><td colspan=\"2\" ><strong><?php echo DT_ADDITIONAL_INFORMATION;?></strong></td>
<?php
/*
for($i=0;$i<$n;$i++)
{
$rowCustom=$rowCustoms[$i];
?>
<tr><td><?php echo $rowCustom->label?>:</td><td><input type=\"text\" class=\"inputbox\" name=\"<?php echo $rowCustom->name?>\" size=\"<?php echo $rowCustom->field_size?>\"></td></tr>
<?php
}
*/
for($i=0,$n=count($rowCustoms);$i<$n;$i++)
{
$rowCustom=$rowCustoms[$i];
if($_SESSION[\'register\'][\'reg_type\'] == \'reg_individual\'){
}else{
if($rowCustom->group_behave==\'1\'){
continue;
}
}
?>
<tr>
<td width=\"100%\" align=\"left\" valign=\"top\">

<?php if($rowCustom->required){echo \"<span class=\'required\'>
