ช่วยด้วยครับ error expecting T_STRING or T_VARIABLE or T_NUM_STRING

				<?php
					$num = 10;
					$num += 5;
					while($objResult = mysql_fetch_array($objQuery)){
						echo "<tr>";
						if($num==15){
							echo "<td id='tdbgred'><?=$objResult["customer"];?></td>";
							echo "<td id='tdborderred'><?=$objResult["incident"];?></td>";
							echo "<td id='tdborderred'><?=$objResult["stime"];?></td>";
							echo "<td id='tdborderred'><?=$objResult["ltime"];?></td>";
							echo "<td id='tdborderred'><?=$objResult["sla"];?></td>";
						}else{
							echo "<tr id = 'tdbggreen' >";
							echo "<td>SCG</td>";
						}
						echo "</tr>";
					}
				?>
