Validation with js of two dimensional array

[kaarmen]

In html i have some question, and the answers are radio buttons ...
the names of variables in html are array ... like question[1], question[2] ... etc.
and every question has multiple value, depending of the answer.


[HTML]<form action="thx.php" method=POST name=form onSubmit="return check(this)">[/HTML]


In javascript i have to determinate if the question is answered, if it is not then return false ...

function check(form) {
 
 
    a=0;
    for (i=0;i<form.question[1].length;i++){
    if (form.question[1][i].checked===true)  {a=1;}
    }
    if (a==0) {
    alert("question[1] no.1: You didn't answer the question");
    return false;
    }
}

Everything work fine until i changed my variables into arrays.
What is wrong now?

This is surely a problem

form.question[1][i].checked===true

You shouldn't have ===, just == :)
