Script to force a radio button selection...

I'm querying a database with ASP that lists selections with radio buttons, and it lists anywhere from zero to 30 records. I have this code to force a selection before going to the next page:

<script language="JavaScript">
function checkForm(theForm) {
msg = "";
qTrain = theForm.schedule_chosen;
qCheck = false;
for(i=0;i<qTrain.length;i++){
if(qTrain[i].checked==true){
qCheck = true;
}
}
if (qCheck == false) {
msg += "You must choose a shift";
}
if (msg>"") {
alert (""+msg);
return false
}
}
</script>

It works just fine when I have more than 1 record listed, but when there is only 1 listed it keeps prompting the user with "You must choose a shift". Any idea what's wrong in this script? If it helps, this is my code for the radio buttons:

Response.Write "<tr><td><input type='radio' name='schedule_chosen' value='"&rs2("num")&"'>" & rs2("11_26") & "</td></tr>"

Any help is much appreciated.

try this

<script language="JavaScript">
function checkForm(theForm) {
var msg = null;
qTrain = theForm.schedule_chosen;
qCheck = false;
for(i=0;i<qTrain.length;i++){
if(qTrain[i].checked==true){
qCheck = true;
}
}
if (qCheck == false) {
msg += "You must choose a shift";
}
if (msg) {
alert (""+msg);
return false
}
}
</script>
