我如果没有加onChange的话，是没有错误的，就是不加onChange而改多加一个submit按钮也是没问题的，就是在select里中的onChange加submit()有问题。

我在一台没设服务的机子（即不能运行JSP和ASP等服务器代码）来调你的程序没发现有错误。我也试过把你的代码去掉服务器代码部分来调试也没发现你说的错误。所以我怀疑你的错误是在服务器代码部分，检查一下看看。。。

以上的方法(包括阿水的两种)都试过了，还是不行，报一样的错。

你的Form对象的id和name不相同，
把它们改成相同，或者只用一个试试。

问题在于，用select_sort不能引用Form对象，但如果select_sort是form标签的id属性的值就可以了。

法一：
---------------------------------
.....
<form id = "select_sort"> <!--注意：id属性，而不是name属性 -->
<select name = "sort" onChange = "select_sort.submit()">
<option value = "goodsid">货品ID</option>
<option value = "goodsqty">货品数量</option>
<option value = "customername">客户名称</option>
</select>
</form>
......
---------------------------
法二：
---------------------------------
.....
<form name= "select_sort">
<select name = "sort" onChange = "this.parentNode.submit()">
<option value = "goodsid">货品ID</option>
<option value = "goodsqty">货品数量</option>
<option value = "customername">客户名称</option>
</select>
</form>
......

上面的代码我试了,没问题.
我另外加了一下<input type = "submit" name = "submit" />后，再按submit却可以，是怎么回事，我想它选定就提交，不要再按submit了。
有这种可能.我记得以前我把submit变灰后,用语句提交不了.
我现在用的是IE6,没有这个问题.

我觉得你实在不行就写一个函数：
<script language=javascript>
function ItemChange()
{
form.action="";
form.submit()
}
</script>
<script language=javascript>
function ItemChange()
{
form.action="";
form.submit()
}

改成下面的试试
<select name = "sort" onChange = "this.form.submit()">
<select name = "sort" onChange = "this.form.submit()">
