I have the following form segment:
Code:
			<table width="90%" border = "0" style="margin-left:40px; 	font-family: helvetica, ariel, sans-serif; font-size: 0.95em; color: #2D8AB9;">
				<tr style="height:3em">
					<td width="2em"><input type="checkbox" name="skipperReg" value="<?php echo $skipperFee ?>" /></td>
					<td width="12em">Registration Fee</td>
					<td width="4em" style="text-align:right">$<input type="text" name="total" readonly="readonly" size ="2" value="<?php echo $skipperFee ?>" /></td>
					<td width ="20em">&nbsp;</td>
				</tr>
				<tr>
					<td ><input type="checkbox" name="guestReg" value="<?php echo $guestFee ?>" /></td>
					<td>Guest Fee</td><td style="text-align:right">$<input type="text" name="total" readonly="readonly" size ="2" value="<?php echo $guestFee ?>" /></td>
					<td>&nbsp;&nbsp;# Guests&nbsp;<input type="text" name="GuestQty" size="2" /></td>
				</tr>
				<tr>
					<td ><input type="checkbox" name="miscAmt"/></td>
					<td>Misc</td><td style="text-align:right">$<input type="text" name="miscTotal" size ="2" /></td>
					<td>&nbsp;&nbsp;List details&nbsp;<input type="text" name="miscDetails" size="15" /></td>
				</tr>
				<tr style="height:2em"><td >&nbsp;</td>
					<td>Total</td><td style="text-align:right">$<input type="text" name="total" readonly="readonly" size ="2"></td>
				</tr>
			</table>
I need a JavaScript that will
If skipperReg is checked, add skipperFee value to the total
If guestReg is checked, add guestFee value times guestQty to the total
If miscAmt is checked, add miscTotal value to the total
Display the new total each time the other inputs are changed.

TIA,
