         $result2 = mysql_query($sql2);
	$Num_Rows2 = mysql_num_rows($result2);
	$result2 = mysql_query($sql2);
	         echo "<select name=MemberTypeID id=MemberTypeID class=input>";
	         echo "<option value=0>เลือกประเภสมาชิก";
	While($row2= mysql_fetch_array($result2)){
	          $MemberTypeID  = $row2["MemberTypeID"];
	          $MemberType = $row2["MemberType"];

?>
	<option value="<? echo "$MemberTypeID"; ?>"><? echo "$MemberTypeID"; ?>-<? echo "$MemberType"; ?> 
<?
 	 } 
	echo "</option></select>";
