Would appreciate any help from anyone... the below PHP contains a list of items from a txt file, next to each item is a text box for the user to enter the qty, by default set to 1. I'm trying to clear the box when the user clicks on a text box, any ideas?

```
<input type='text' id='qty' name='$partno' size='1' value='0'>

```

So far I've tried using JavaScript but had no luck.

```
        <script>
        function validateName()
        {
            var x=document.forms["purchase"]["visitor"].value;
            if (x==null || x=="")
            {
                alert("Visitor name must be entered");
                return false;
            }
        }

        function name()
        {  
            document.getElementById('qty').value = "";
        }
    </script>
</head>

<body>

    <h1>Items Available</h1>

    <form id="purchase" name="purchase" action="confirm.php" method="post" onsubmit="return validateName()">
        <table>

            <h3>Visitor Name: <input type='text' name='visitor'></h3>
            <tr><th></th><th></th><th></th><th>Price</th><th>QTY</th></tr>

            <?php
            if (!($data = file('items.txt'))) {
                echo 'ERROR: Failed to open file! </body></html>';
                exit;
            }
            foreach ($data as $thedata) {

                list($partno, $name, $description, $price, $image) = explode('|', $thedata);
                echo "<tr><td><img src='$image' width='60' height='60' alt='image'></td><td><h3>$name</h3></td><td>&nbsp;&nbsp;&nbsp;&nbsp;$description</td>
                    <td>&nbsp;&nbsp;&nbsp;&nbsp;<b>&pound;$price</b></td><td><input type='text' id='qty' name='$partno' size='1' value='0'></td></tr>";
                //<input type='text' size='1' name='partno_qty' value='1'</td>
            }
            ?> 

        </table>

        <input type="submit" value="Purchase">
        <input type="reset" value="Clear">

    </form>

```
