도와주세요 글 수정시 셀렉트에 값이 안넘어오네요

글 수정 누르면 Model Tpye에 select 에 값이 안넘어오고 자꾸 다시 선택 하게끔 하네요 ㅠㅠ
날짜선택하는 거나 다른 셀렉트들은 잘 되는데요..



<script language="JavaScript" src='<?=$board_skin_path?>/cars.js'></script>
<select name=wr_8 onChange="wr_8change()" value="<?=$write[wr_8]?>" itemname="Model Tpye" style="width:100px; height:25px;" required>
<option value="<?=$write[wr_8]?>"><?=$write[wr_8]?></option>
</select>
<select name=wr_9 onChange="wr_9change()" value="<?=$write[wr_9]?>" style="width:100px; height:25px;">
<option value="<?=$write[wr_9]?>"><?=$write[wr_9]?></option>
</select>
<select name=wr_10 value="<?=$write[wr_10]?>" style="width:100px; height:25px;">
<option value="<?=$write[wr_10]?>"><?=$write[wr_10]?></option>
</select>
<input type=hidden name=sop value='and'>
