Single Dynamic Checkbox record

Question

Hi,
I am displaying 1 record with dynamic checkbox with the below
statement
select empno, ename, job,wwv_flow_item.checkbox(1, rownum) pr from emp where rownum = 1
When i hit the Save button i am using onMouseDown event and calling
the javascript function to make sure the checkbox is checked, and then i am submitting the Page.
For SAVE button in the button attributes i have this code: onMouseDown="Members_Selected();".
The below code is used in HTML HEADER:
<script language="JavaScript">
function Members_Selected(){
var bflag;
bflag = false;
alert('total count of check boxes:'+document.forms[0].f01.length);
for (var i=0; i<document.forms[0].f01.length; i++)
if (document.forms[0].f01.checked == true )
bflag = true;
if (!bflag)
alert("Please select Atleast 1 Member.");
return false;
if (confirm("Are you sure you want to assign the selected members !!"))
doSubmit('SAVE');
else
return false;
return true;
}</script>
Below is the problem i see When i HIT the SAVE BUTTON, by Selecting* the checkbox :*_
I see the java script alert : total count is shown as "undefined"
and another javascript alert : 'Please select Atleast 1 Member',
and the page is not submitted.
Have anyone encountered this problem, i have tested in apex workspace too, i see the same problem.
Any help or suggestion is appreciated
Thanks

Hello:
Check if this modified JS works for you function Members_Selected(){
var bflag;
bflag = false;
var arr=new Array();
obj=document.forms[0].f01;
if (obj.length)
    arr=obj;
else
    arr[0]=obj.value;
alert('total count of check boxes:'+arr.length);
for (var i=0; i<arr.length; i++)
if (arr.checked == true )
bflag = true;
if (!bflag)
alert("Please select Atleast 1 Member.");
return false;
if (confirm("Are you sure you want to assign the selected members !!"))
doSubmit('SAVE');
else
return false;
return true;
