Here you are:-

<form name = "myform">
<input name = "myname" type = "checkbox" value = "Red" onclick="count()"> RED <br>
<input name = "myname" type = "checkbox" value = "Blue" onclick="count()"> BLUE <br>
<input name = "myname" type = "checkbox" value = "Green" onclick = "count()"> GREEN <br>
<input name = "myname" type = "checkbox" value = "Yellow" onclick = "count()"> YELLOW<br><br>
You have checked <input type = "text" size = "2" name= "totChecked" value = "0" readonly> checkboxes

<script type = "text/javascript">
function count() {
var totBoxes = 0;
for (i = 0; i < myform.myname.length; i++) {
if (myform.myname[i].checked) {
totBoxes ++;
document.myform.totChecked.value = totBoxes;

BTW, the time to say "thanks" is afterwards, not beforehand which gives the - doubtless unintended - impression that you take other people's voluntary unpaid assistance for granted. Or as British politician Neil Kinnock put it, "Don't belch before you have had the meal." Prefer to use "please" beforehand (as you have done) and if you find a response helpful then you can use the "Thank User For This Post" button.
