asp_web_howto thread: testing within loop

Hi, In this form, the user checks items to delete and which email
message to send about each item.
How can I force the user to check one and only one message for each deleted
item? Javascript? How? I tried using the .checked property, but that just
paused the script, and on the next click sent the user to the next page.
I'm using PWS, by the way.
With my current code, it's possible to check boxes like this:
Item Delete Msg1 Msg2
A checked checked checked
B checked
C
This would send 2 arrays to next page: Item(A,A) and Msg(msg1,msg2). On
the next page, I pair up sequential values from each array. So in the case
above, both messages get sent for Item A, and none for Item B. This would
cause problems.
I tried using radio buttons and combo boxes instead of checkboxes. They
didn't work right either.
The form code:
response.write
"<table><tr><td>Item</td><td>Delete</td><td>Msg1</td><td>Msg2</td></t
r>"
Do while not rs.eof
response.write "<tr><td>"&rs("Item")&"</td>"
response.write "<td><input type=checkbox name=Item
value='"&rs("Item")&"'></td>"
response.write "<td><input type=checkbox name=Msg value=msg1></td>"
response.write "<td><input type=checkbox name=Msg value=msg2></td></tr>"
rs.movenext
Loop
response.write "</table>
Thanks in advance
moderator: I'm resending this (cleaned up a little). Last time it was
posted to asp_forms, with no replies. Could we try asp_databases, and/or
javascript this time?

In the <HEAD> you could write;
<SCRIPT language="JavaScript">
<!--
function radioCBox (checkbox) {
var checkboxGroup = document.options.myCheck;
for (var c = 0; c < checkboxGroup.length; c++)
if (checkboxGroup[c] != checkbox)
checkboxGroup[c].checked = false;
return checkbox.checked;
}
//-->
</SCRIPT>
and then in the <BODY>;
<form name = "options">
<%
Do while not rs.eof
Response.Write("<tr><td><input TYPE='CHECKBOX' NAME='myCheck'")
Response.Write(" value='")
Response.Write(rs("item"))
Response.Write("' ONCLICK='return radioCBox(this);'")
Response.Write("></td></tr>")
rs.movenext
Loop
%>
</form>
That should do it.
Vince.
