Advice on how to delete a mysql row using my form

Hi,
I am very new to php and am struggling to work out how to delete a portfolio item (a row from my database using my form which is here): http://www.spencercarpenter.co.uk/portfolioAppFiles/simpleForm.php
The problem comes I think because I already have one submit button on the page as you can see.
Ideally when pressed the delete button will remove the row from the database with the same name that is showing in the top drop down box and either go to a page with a 'delete successfull' message or the message wil appear next to the button.
Here is the code for the page:
Code: <?php
include('connectToDB.php');
include('populateDropDownList.php');
include('buildFileList5.php');
//include('deleteCurrentItem.php');
?>
<html>
<head>
<script type="text/javascript">
var existingPortfolioItems = new Array();
function chkFrm(el){
if(el.selectedIndex == 0){
alert("Please choose an option");
return false
}
else{
el.form.submit();
}
}
function hello(){
//alert("Hello It works");
var result = "boo";
location.replace("deleteCurrentItem.php?result"+ result);
//location.href = "deleteCurrentItem.php?Result=" + Result;
}
function updateImg(ele, img) { // using arguments makes this function reusable for multiple items
// ele = dropdown object
// img = image object
document.getElementById(img).src = "uploaded/thumbs/" + ele.value;
//document[img].alt = ele.value;
}
</script>
</head>
<body>
<h1>Select Existing Item:
</h1>
<form action"deleteCurrentItem.php" method="POST" >Existing Item:
<select name="name" onChange="chkFrm(this)">
<option value="Choose" <?php if (!(strcmp("Choose", $_POST['name']))) {echo "SELECTED";} ?>>Choose Portfolio Items</option>
<?php do { ?>
<option value="<?php echo $row_PortfolioItems['id']?>"<?php if (!(strcmp($row_PortfolioItems['id'], $_POST['name']))) {echo "SELECTED";} ?>><?php echo $row_PortfolioItems['name']?></option>
<?php
} while ($row_PortfolioItems = mysql_fetch_assoc($PortfolioItems));
$rows = mysql_num_rows($PortfolioItems);
if($rows > 0) {
mysql_data_seek($PortfolioItems, 0);
$row_PortfolioItems = mysql_fetch_assoc($PortfolioItems);
}
?>
</select>
