Problem with drop down menus

Hello there,

I am struggling with a problem I'm experiencing with drop down menus and I would really appreciate any help. The code I am working on is as follows:

foreach($sub_codes as $a_code)
{				
	$sql2 = "SELECT MD_CL_Subject, MD_Attainment, IF_TA_SubCode, IF_TA_ID, CS_CL_SubjectCode 
FROM `MainData`, `ClassStudent`, `ifile_Target`
WHERE MainData.MD_PU_AdNo = ClassStudent.CS_PU_AdNo
AND MainData.MD_PU_AdNo = ifile_Target.IF_TA_PU_AdNo
AND ClassStudent.CS_PU_AdNo = ifile_Target.IF_TA_PU_AdNo
AND MainData.MD_CL_SubjectCode = ClassStudent.CS_CL_SubjectCode
AND MainData.MD_CL_SubjectCode = ifile_Target.IF_TA_SubCode
AND ClassStudent.CS_CL_SubjectCode = ifile_Target.IF_TA_SubCode
AND MainData.MD_CL_ClassName = ClassStudent.CS_CL_ClassName
AND ClassStudent.CS_CL_SubjectCode = '" . $a_code . "' 
AND MD_Semester = '" . $active_check . "'
AND MD_PU_AdNo = '" . $adno . "'
ORDER BY MD_CL_Subject ASC";

include("?????????????");
														
while ($row2 = mysql_fetch_assoc($rst2))
{									echo "<tr>";
									echo "<td align = 'left'><span class = 'style19'>" . $row2['MD_CL_Subject'] . "</span></td>";
									echo "<td><span class = 'style19'>" . $row2['MD_Attainment'] . "</span></td>";
									echo "<td>" . $row2['IF_TA_ID'];
									echo "<td><select name = 'target' value = '$target'>";
										echo "<option value = '1'>1</option>";
										echo "<option value = '2'>2</option>";
									echo "</select>";
									echo "</td>";
									echo "<input type = 'hidden' name = 'target_id' value = '" . $row2['IF_TA_ID'] . "' />";
									?>
									<td align = "center">
										<input type = "submit" name = "submit_target" value = "Save Target Grade" onclick = 'javascript: return confirm("Are you sure you want submit this order?")' />	
									</td>
							<?php //}
							}	
						}	     
						echo "</tr>";

PHP:

What this code does is create a form for a student with all of their subject and grades for each subject with a drop down box for them to select a Target grade to aim for. Basically the problem I am experiencing is that no matter which submit button I press the 'target_id' printed off is always that of the last row in the table.

Any help with this matter would be greatly appreciated.

Regards,

Karl.
