try this...this code allows you to check and uncheck all checkboxes

<!--- place above checkbox--->
<SCRIPT>
function checkBoxes (form, check) {
var flagThis = false;
  for (var c = 0; c < form.elements.length; c++)
      flagThis = false;
      if (form.elements[c].type == 'checkbox')
        form.elements[c].checked = check;
        flagThis = true;
      if (flagThis)
        form.elements[c].checked = enabled;
}
</SCRIPT>


<!--- to check all checkboxes --->
<INPUT TYPe="CHECKBOX" NAME="applyToAll" ONCLICK="checkBoxes(this.form, this.checked)" VALUE="yes">

That's odd, well try this piece of code. As this works just fine in my browser. If you have SP2 for XP then allow blocked content.


<HTML>
<HEAD>
<TITLE>

<SCRIPT>
function checkBoxes (form, check) {
  for (var c = 0; c < form.elements.length; c++)

      form.elements[c].checked = check;
}
</SCRIPT>
</HEAD>
<BODY>
<FORM NAME="formName">
Check all
<INPUT TYPE="checkbox" NAME="checkAll"
       ONCLICK="checkBoxes(this.form, this.checked)"

thanks, second code works fine, and nope I did not install SP2 yet, I'm in the middle of a project, not taking any risks.
now, this works fine to select all but to if i select a few and want to deselect them, i have to click your check box twice!
is there a way around this?
thanks
