Help with javascript error "..is null or not an object"

Hi, I have a javascript that is supposed to calculate a discount percentage:

<SCRIPT language=JavaScript>
<!--
function perc1() {
 discPerc = document.form1.discPerc.value/100;
 discTotal = discPerc*document.form1.subTotal.value;
 document.form1.discTotal.value = discTotal
 }
 //-->
</SCRIPT>

<tr>
<td colspan="2" align="right"><INPUT onclick=perc1() type=button value=Calculate>&nbsp;&nbsp;<i><%=discCode%></i>&nbsp;&nbsp;<input type="text" name="discPerc" size="4" maxlength="10" value="<%=moneyD(formatNumber(discPerc,2))%>" />%&nbsp;&nbsp;<b>Discount Code:&nbsp;&nbsp;</b></td>
<td nowrap=""><%=pCurrencySign%><input type="text" name="discTotal" size="5" maxlength="10" value="<%=moneyD(discTotal)%>" />(-)</td>
</tr>

BUT I keep getting this error:

document.form1.discPerc.value is null or not an object.

The form is named form1. Can anyone help?
