for (i = 0; i < document.checks.user.length; i++) //for all check boxes

{

    if (document.checks.user[i].checked == true )

    {

        document.checks.submit();

        return 0;

    }

}



<body>

<form action= method=POST name=checks ID=Form2>

  I have a bike:

  <input type=checkbox name=user value=Bike ID=Checkbox1>

  <br>

  <br>

</form>

<input type=button value=Delete 

    class=btn onclick=sub_delete() 

    onmouseover=hov(this, 'btn btnhov') onmouseout=hov(this, 'btn') 

    id=Button1 name=Button1 

/>

</body>

as you probably already know when there is only one check box left document.checks.user.length = undefined. Whats the most efficient way to make sure that when there is only one check box, it will be deleted. I was thinking just thinking to add it as a seperate if statement before the if statement here.....any suggesstions.

Thanks.
