Another PHP question!

New to PHP and I am trying to print out a form, with multiple checkboxes. I have successfully used PHP to run options in a drop down menu. However I am still having problems in print to the screen any kind of form through php.

print "<tr>
<td>
<input type="submit" name="Delete" value="Submit" />
</td>
<td>
<b>Product ID</b>
</td>
<td>
<b>Name</b>
</td>
<td>
<b>Description</b>
</td>
<td>
<b>Picture</b>
</td>
<td>
<b>Category</b>
</td>
<td>
<b>Supplier</b>
</td>
<td>
<b>AdminID</b>
</td>
</tr>";

if($r = mysql_query($query)){
while($row = mysql_fetch_array($r)){

print "<tr>
<td><input type="checkbox" name="delete[{$row}]" value="{$row}" />
</td>
<td>{$row}</td>
<td>{$row}</td>
<td>{$row}</td>
<td>{$row}</td>
<td>{$row}</td>
<td>{$row}</td>
<td>{$row}</td>
</tr>";

The form and table opening tags lie outside the php code. I have seperated the code for easy reading.
