Thanks for such fast reply!
Ok, I removed {include file="main/register_additional_info.tpl" section="P"} from
/main/register_personal_info.tpl and added
<table border="0" cellpadding="0" cellspacing="0" width="643">
<tr>
<td align="right">field name text(label)</td>
<td> </td>
<td nowrap="nowrap">
<input type="text" name="dob" id="dob" value=""><font face="Arial" size="2" color="#FF0000">(Example 05/25/1975 . Must be 18 or older to order!)</font>
</td>
</tr>
</table>
at the very end of template, as a result - I get the field, get the note I wanted accross from it, but layout still messed up. It appears, personal information block looks fine, but everything else around gets gray background instead of default wite, and all other blocks (addresss, passwords, etc) moved to the right?
Is there certain place in template where I need to insert the code?
