hi guys,

i have a little problem in the following JS Code.
I have 44 Form elements.
The code below checks if every single element is klicked.
But the code should check, if only one of the 44 elements is clicked.
What I`m doing wrong?



-------------------------

function checkform()
{

var i = 0;
var number = 45;

while (i< number){

if (document.form.elements[i].checked == false) {

alert("Please klick...");

return false;
}
i ++;

}
}

thx
mt
