CSS验证的问题

我这里有一段代码
JScript code:
<script type="text/javascript">function CheckVote(obj){var oSel=obj.getElementsByTagName("input");var iLength=oSel.length;for(var i=0;i<iLength;i++){var flag=false;if(oSel[i].type=="checkbox" || oSel[i].type=="radio"){if(oSel[i].checked==true){flag=true;break;}}}if(flag==false){alert("请选择选项参与我们的调查");oSel[0].select();}return flag;}</script>



在进行验证时出现这种错误

HTML code:
Validation Output: 6 Errors

1. Error Line 320, Column 144: character ";" not allowed in attribute specification list

…th=oSel.length;for(var i=0;i<iLength;i++){var flag=false;if(oSel[i].type=="ch
