does anyone know how to do this???

["Jason" <jason@haffey.com>]

I have been racking my brain to figure out how they do this...

If you go to just about any web based email, you will have Check 
Boxes down the side next to each email.  There is the one check box 
at the top that if you click, all the rest "check up".  That part 
already did (with javascript) but then when I try to do a deleted, 
mark read, or etc. I cant figure out how to run a loop to check each 
checkbox.

here is the basic code I have...(the HTML)

<script language="javascript" type="text/javascript">
function checkAll()
{
document.messages.MSGS1.checked = document.messages.MA.checked;
document.messages.MSGS2.checked = document.messages.MA.checked;
document.messages.MSGS3.checked = document.messages.MA.checked;
}
</script>

<input type="checkbox" name="MA" onclick="checkAll();"></td>
<input type="checkbox" name="MSGS1" value="ON"></td>
<input type="checkbox" name="MSGS2" value="ON"></td>
<input type="checkbox" name="MSGS3" value="ON"></td>

and so on......

but when I click the submit button I run into an issue as I dont know 
how to do a loop that can create the term:

for($i=1;$i<=$msg_count;$i++){
    if(MSGS$i==true){do this)
}

I did try to do an array but that didnt work with my loop nor my 
javascript:

<script language="javascript" type="text/javascript">
function checkAll()
{
document.messages.MSGS.checked = document.messages.MA.checked;
document.messages.MSGS.checked = document.messages.MA.checked;
document.messages.MSGS.checked = document.messages.MA.checked;
}
</script>

<input type="checkbox" name="MA" onclick="checkAll();"></td>
<input type="checkbox" name="MSGS" value="ON"></td>
<input type="checkbox" name="MSGS" value="ON"></td>
<input type="checkbox" name="MSGS" value="ON"></td>


I just want to finish this part of my script so if anyone is willing 
to help me out so I can move on I would be really really happy, 
thanks in advance.
