<input name="EmailList_<?php echo $RepeatSelectionCounter_1; ?>" type="hidden" id="EmailList_<?php echo $RepeatSelectionCounter_1; ?>" value="Y" <?php if (!(strcmp($row_rsEmail['EmailList'],"Y"))) {echo "checked=\"checked\"";} ?> />
change it to N
<input name="EmailList_<?php echo $RepeatSelectionCounter_1; ?>" type="hidden" id="EmailList_<?php echo $RepeatSelectionCounter_1; ?>" value="N" />
