    // if (ACCOUNT_DOB == 'true') $dob = tep_db_prepare_input($HTTP_POST_VARS['dob']);
    // first line
    if (ACCOUNT_DOB == 'true') $dob = tep_db_prepare_input($HTTP_POST_VARS[dob_month] . '/' . $HTTP_POST_VARS[dob_day] . '/' . $HTTP_POST_VARS[dob_year]);
    // last line

2. between lines 345 - 372
                <!-- <td class="main"><?php echo tep_draw_input_field('dob') . ' ' . (tep_not_null(ENTRY_DATE_OF_BIRTH_TEXT) ? '<span class="inputRequirement">' . ENTRY_DATE_OF_BIRTH_TEXT . '</span>': ''); ?></td> -->
                <td class="main">
                <?php
                // 1. first line
                
                for ($i=1; $i<32; $i++) {
	            $dob_day[] = array('id' => sprintf('%02d', $i), 'text' => sprintf('%02d', $i));
            	}
            	
				for ($i=1; $i<13; $i++) {
				$dob_month[] = array('id' => sprintf('%02d', $i), 'text' => strftime('%B',mktime(0,0,0,$i,1,2000)));
				}

				$today = getdate();
				$first_year = $today['year'] - 77; 
				$last_year = $today['year'] - 17;
				for ($i=$first_year; $i < $last_year; $i++) {
				$dob_year[] = array('id' => sprintf('%02d', $i), 'text' => sprintf('%02d', $i));
				}

                
				echo tep_draw_pull_down_menu('dob_day', $dob_day);
				echo tep_draw_pull_down_menu('dob_month', $dob_month);
				echo tep_draw_pull_down_menu('dob_year', $dob_year);
                
                // last line
                ?>
                </td>

but the BTS makes in ms2-max makes the files different and i cannot figure out how to edit this into mine. Any info will help.
