this program inserts data (correctly) into fields b4 update but I get the error message when I submit. Can someone tell me what is wrong with my code?

<html><head>
<!--when the paidamt is keyed in, the current date, pd & paidsum are autoinserted-->
<script>
function $_(IDS) { return document.getElementById(IDS); }
function calculate_paid() {
   var pd = document.getElementById("pd");
   var datepaid = document.getElementById("datepaid");
   var amtdue = document.getElementById("amtdue");
   var paidamt = document.getElementById("paidamt");
   var paidsum = document.getElementById("paidsum");
// ********************set up date**********************
  var dateNow = new Date();
  var dayNow = dateNow.getDate();
  var datePaid = (dateNow.getMonth()+1)+"/"+dateNow.getDate()+"/"+dateNow.getFullYear();
datepaid.value = datePaid;
// ***************end date setup*************************
// ********accumulate charges into paidsum & set up pd*** 
amtdue.value = parseFloat(amtdue.value);
paidsum.value = parseFloat(paidsum.value) + parseFloat(paidamt.value);
pd.value = "P";
// ********************* end of calcs ******************

Jeez, you certainly don't believe in separating your php/html/js do you??!

1. Try to post to a different page (avoids the reload/refresh double submit)
2. Which form is giving you the problem?

Sorry, this is giving me a headache.

sorry I had trouble finding how to separate the two. Yeah I'm sorry 'bout your headache

:} No to worry. Which form is causing the issue?

OK, I tidied up the code somewhat. Some people like it like this. It's a matter of personal preference.

...
?>

	<form action="#" method="post"><strong>Invoice Payment :</strong><br /><br />
	<table cellspacing="0" cellpadding="0" border="1">
		<tr>
		  <th>Inv#</th>
		  <th>ord#</th>
		  <th>Name</th>
		  <th>Description</th>
		  <th>Paid Amt</th>
		  <th>Amt Due</th>
		  <th>Date Paid</th>
		  <th>Code</th>
		  <th>Total</th>
		  </tr>
	<?php
	while($row = mysql_fetch_assoc($result)){
	extract($row);
	?>
		<tr>
			<td><input type="text" size="5" name="invnum" value="<?php echo $invnum;?>" /></td>
			<td><input type="text" size="5" name="ordernum" value="<?php echo $ordernum;?>" /></td>
			<td><input type="text" size="25" name="bname" value="<?php echo $bname;?>" /></td>
			<td><input type="text" size="25" name="descr" value="<?php echo $descr;?>" /></td>
			<td><input type="text" size="7" id="paidamt" name="paidamt" value="<?php echo $paidamt;?>" onBlur="calculate_paid(this);" /></td>
			<td><input type="text" size="7" id="amtdue" name="charges" value="<?php echo $amtdue;?>" /></td>
			<td><input type="text" size="10" id="datepaid" name="datepaid" value="<?php echo $datepaid;?>" onBlur="calculate_paid(this);" /></td>
			<td><input type="text" size="1" id="pd" name="pd" value="<?php echo $pd;?>" onBlur="calculate_paid(this);" /></td>
			<td><input type="text" size="7" name="paidsum" value="<?php echo $paidsum;?>" onBlur="calculate_paid(this);" /></td>   
		</tr> 
	<?php
	}
	?>
	</table>
	<input type="submit" name="update" value="Make Payment" />
	</form>
	<?php
	}else{
		echo "No listing for invoice no. $invnum.<br />Please select another.<br />";
	}
}
if(isset($_POST["update"])){
	$sql = "UPDATE payments SET
	pd = '" . mysql_real_escape_string($_POST['pd']) . "',
	datepaid = '" . mysql_real_escape_string($_POST['datepaid']) . "',
	paidamt = '" . mysql_real_escape_string($_POST['paidamt']) . "',
	amtdue = '" . mysql_real_escape_string($_POST['amtdue']) . "',
	paidsum = '" . mysql_real_escape_string($_POST['paidsum']) . "'
	WHERE invnum='".$_POST["invnum"]."'";
	// **********************************************
	mysql_query($sql) or die("Update query failed.");
	
	
	...
?>

your code got this message:

UPDATE payments SET pd = 'P', datepaid = '4/19/2011', paidamt = '169.60', amtdue = '', paidsum = '169.6' WHERE invnum='150'

paidsum dropped a zero and no update. Closer!

<input type="text" size="7" id="amtdue" name="charges" value="<?php echo $amtdue;?>" />

This is because the id ia amtdue but the name is charges. Change charges to amtdue.

<input type="text" size="7" id="amtdue" name="charges" value="<?php echo $amtdue;?>" />

This is because the id ia amtdue but the name is charges. Change charges to amtdue.

I made the change and the results were the same. I put an id in the paidsum but the results were the same.? This poor noob is perplexed.

Well it seems to be you update query. echo it out:

echo $sql;

and post it here

I'm not sure I understand what you're suggesting
