不太熟悉PHP编程，为什么总报缺少‘）’错误？

劳大家帮我看看，为什么总是报if(form1.2_ytbyx.value==""){错误，说缺少‘（’？万分感谢！
            <input type="button" name="Submit" value="提交" onClick="process() "></td>
      <script>
function process(){

//alert("开始检验!");
if(form1.2_ytbyx.value==""){
alert("您所输入的分值不能为空!");
form1.2_ytbyx.select();
}else if(checkscore20(form1.2_ytbyx.value)!=true){
alert("您输入的分值不正确！当前分值不应超过20分!");
form1.2_ytbyx.select();
return(false);
}else{
var ytbyx = parseInt(document.getElementById("2_ytbyx").value);
//alert("您输入的数值通过检验！请确认!");
}

完全是js的代码，没看到php的
因为报错只有这一段所以摘录了一下，主要程序如下：

改下input的name命名试试，不要数字开头
听楼上的建议。所有的input改为名字_数字的形式。
如1_mnbr  =>  mbnr_1
否则会报js warning 的。
不明白的是，你的怎么会报php错误。
