Arkadaşlar şu kodda tabloda mouse'u getirince farklı renk almasını sağlamak istiyorum. Ancak ne yaptıysam olmadı. Kodun neresinde yanlışlık var acaba?

<tr onMouseover="this.style.backgroundColor='#C0C0C0';this.style.fontWeight='bold';" onMouseout="this.style.backgroundColor='#f1f1f1';this.style.fontWeight='normal';">
						<td bordercolor="#000000" align="center" bgcolor="#f1f1f1"><?=$mac[3]?></td>
						<td bordercolor="#000000" align="center" bgcolor="#f1f1f1" ><?						
						if($mac[16]=="FT"){
						echo "Bitmiş"; }
						elseif($mac[16]=="HT"){
						echo "Devre Arası";
						}else{
						echo "<font color='red'>".$mac[16]."</font>";
						}?></td>
						<td bordercolor="#000000" align="center" bgcolor="#f1f1f1"><?=$mac[4]?></td>
						<td bordercolor="#000000" align="center" bgcolor="#f1f1f1"><?=$mac[9]?> - <?=$mac[10]?></td>
						<td bordercolor="#000000" align="center" bgcolor="#f1f1f1"><?=$mac[5]?></td>
						<td bordercolor="#000000" align="center" bgcolor="#f1f1f1"><?=$mac[11]?> - <?=$mac[12]?></td>
						<td bordercolor="#000000" align="center" bgcolor="#f1f1f1"><?=$mac[6]?></td>
						<td bordercolor="#000000" align="center" bgcolor="#f1f1f1"><?=$mac[7]?></td>
						<td bordercolor="#000000" align="center" bgcolor="#f1f1f1"><?=$mac[8]?></td></tr>
