first, name all the checkboxes the same (say.... "cbox"), then use the below
function with the onclick action
function checkBoxes(theForm){
var counter = 0;
for( i=0; i<theForm.cbox.length(); i++ ){
if( theForm.cbox[i].checked ){
counter ++;
lastChecked = i;
}
}
if( counter <= 5 ){
alert("You can only check 5");
theForm.cbox[lastChecked].checked = false;
}
}
<input type="checkbox" name="cbox" onclick="checkBoxes(this.form);">

Subject: javascript form help
does anyone know where i can find a script that will limit the user from
chosing more than a certain amount of choices in a checkbox form? the user
can only chose up to 5 choices, but there are many choices that they can
chose from.
any help would be greatly appreciated.
