Hi, my problem is that my variables are not working in javascript. all variables need names without some character at the beginning, this is the stupid thing...Anyways, im trying to make a funtion that makes "select all checkboxes". It is not working so i looked at the page source/info and found out that the variables were not changing.

this is my input:

echo "<input onclick='checkAll(1);' type='checkbox' name='master'/><br/>";

My function:

function checkAll(i)
{
 for(var i=1; i < <?php echo $num; ?>; i++)
 {
  if(document.demo.master[i].checked == true)
  {
   document.demo.message[i].checked = true;
  }
  else
  {
   document.demo.message[i].checked = false;
  }
 }
}

so yes that's it. I can tell you that i also tried without the <i> in: checkAll("i")

Thanks for the help.

EDIT: each checkbox for each messsage has this code:echo "<input style='margin-left:-15px;margin-top:20px;' type='checkbox' name='message' value='$rid' /><br/>";
