Help?

[Highland3r]

i need to change the way this code works.

 

at the moment when the code runs it brings up a default box which calculates the cost by the number of rooms i need it to calculate dependent on number of people.

<form name='booking' method='post' action='reservationform.php' onSubmit='return booking_validate()'>			<input type='hidden' id='arrival_date' name='arrival_date' value='".$this->print_arrival_date()."'>			<input type='hidden' id='leaving_date' name='leaving_date' value='".$this->print_leaving_date()."'>			<input type='hidden' id='nights' name='nights' value='".$this->nights()."'>";			while($result=$db->fetchAssoc()) {				$info .="<div class='rateheader'>							".$result['type_name']."						</div>						<div class='rate'>							<div class='innerrate'>							<p>								".stripcslashes($result['description'])."							</p>							Max Occupants: <b>".$result['max_occupants']."</b><br/>							Max Children: <b>".$result['max_childs']."</b><br/>							Price per night: <b>£".$result['default_price']."</b>						<br/><br/><br/>						Please select number of rooms and click reserve button below 						<table  cellspacing=1 cellpadding=1  border=0>							<tr>								<td> </td>							</tr>							<tr>								<td>Rooms</td>								<td style='display:none' id='adults_td[".$result['room_type_id']."]'>Adults</td>								<td id='price_td[".$result['room_type_id']."]' style='display:none'  >								   <nobr>Total Price</nobr>								</td>							</tr>							<tr>								<td>									<input type='hidden' name='max_adults[".$result['room_type_id']."]' id='max_adults[".$result['room_type_id']."]' value='".$result['max_occupants']."' />									<input type='hidden' name='price_hidden[".$result['room_type_id']."]' id='price_hidden[".$result['room_type_id']."]' value='".$result['default_price']."' />									<select id='number_rooms[".$result['room_type_id']."]' name='number_rooms[".$result['room_type_id']."]' 										onChange='ajax_calculate(".$result['room_type_id'].")'>										<option value='0' selected>0</option>";										for($i=1;$i<=$result['room_count'];$i++) {											$info .="<option value=".$i." >".$i."</option>";										}    									$info .="</select>    								</td>								<td id='adults_td1[".$result['room_type_id']."]' style='display:none;'>								</td>    								<td style='padding-left:12px;display:none;' id='price_td1[".$result['room_type_id']."]' >								  <B>£<span name='price[".$result['room_type_id']."]' id='price[".$result['room_type_id']."]'>0.00</span><input type='hidden' name='price[".$result['room_type_id']."]' value=''></B>								</td>							</tr>						</table>												<input type='submit' class='buttonstyle' name='btn' value='Reserve' title='Reserve this room' /><hr />						<br /><br />											</div>				</div><input type='hidden' name='validate' id='validate' value='0'>";			}			$info .="<script type='text/javascript'>						function ajax_calculate(room_type_id) {        							var price=document.getElementById('price_hidden['+room_type_id+']').value;							var number=document.getElementById('number_rooms['+room_type_id+']').options[document.getElementById('number_rooms['+room_type_id+']').selectedIndex].value;							var number_adults=document.getElementById('max_adults['+room_type_id+']').value;							var total_adults=number_adults*number;							var nights=document.getElementById('nights').value;							if (number!=0) {								document.getElementById('adults_td['+room_type_id+']').style.display='';								document.getElementById('adults_td1['+room_type_id+']').style.display='';								document.getElementById('price_td['+room_type_id+']').style.display='';								document.getElementById('price_td1['+room_type_id+']').style.display='';								document.getElementById('validate').value=1;							}							else {								document.getElementById('adults_td['+room_type_id+']').style.display='none';								document.getElementById('adults_td1['+room_type_id+']').style.display='none';								document.getElementById('price_td['+room_type_id+']').style.display='none';								document.getElementById('price_td1['+room_type_id+']').style.display='none';								document.getElementById('validate').value=0;							}							select_adult=\"<select id='adults[\"+room_type_id+\"]' name='adults[\"+room_type_id+\"]'>\";							for (var i=1;i<=total_adults;i++) {								select_adult+=\"<option value=\"+i+\">\"+i+\"</option>\";                       							}							select_adult+=\"</select>\";							var total_price=number*price*nights;							document.getElementById('adults_td1['+room_type_id+']').innerHTML=select_adult;							document.getElementById('price['+room_type_id+']').innerHTML=total_price;													}						</script>			</form>";

 

So at the moment when you open the program it asks how many rooms you require in my case it is always one but if you select 2 it doubles the price and so on, once you have selected the number of rooms it asks how many people 1 - 4 now doesnt matter what you select it doesnt change the price Help apreciated.
