Javascript baby!
You can change the checked status of a checkbox by...
document.formname.checkboxname[x].checked = true/false;
x being the occurance of that set of checkboxes with the same name, starting
with 0...
So if you know, for instance, that you have 20 checkboxes and you want a
'check all' box...
for (x = 0; x LTE 19; x = x + 1); {
document.formname.check[x].checked = false;
}
I'm sure there's a way to query a set of checkboxes and see how many
elements there are, and set your for loop to that... just don't know it off
the top of my head.
