validate in Javascript

[Anon]

I have a question .I using array in php and I would like to use javascript for validate.
How can I do?
<SCRIPT language=Javascript1.2>

function Validate(form) {
if (!form.fund[0].checked )
{ alert("You missed the question # 1"); return; }
form.submit() }

</SCRIPT>
<? PHP
<input type=checkbox name=$fund[] value=a>
a <br>
<br>
<input type=checkbox name=$fund[] value=b>
b <br>
<br>
<input type=checkbox name=$fund[] value=c>
c <br>
<br>
<input type=checkbox name=$fund[] value=d>
d<br>
<br>
<input type=checkbox name=$fund[] value=e>
e
<INPUT onclick=Validate(form) type=button value="Submit Form">
When I run the script the script has the error can not find the object?
Any idea
Thank You

Hi Jane,
I can suggest two solutions to this
1.Change the Check box names i.e while

generating the check boxes give names like
fund1,fund2,.....and a hidden field which holds the value of total number of check boxes , then you need to write a function(javascript) i think you won't prefer this.
2.Next soultion is (I am assuming that your from has only these check boxes(array))
use this javascript function

function checkEmpty()

{
var flag=true;
var len=eval("document.test.elements.length");
for(var i=0;i<len;i++)
{

if(document.test.elements.type=="checkbox")
{
if(document.test.elements.checked==false)
{
var j=i+1;
alert("You missed the question #"+j);
flag=flase;
break;
}
}

}
if(flag==true){ document.test.submit();}
}

call this function onClick="checkEmpty()"

Note: "test" is the form name.Replace "test" with your form name.

Hope this works........
