Omni portlet - javascript - date field problem

Question

I want to manipulate a database date type field with javascript in omniportlet layout.
In the source tab of omniportlet I use the SQL: (it's very simple for example)
select id, to_char(enddate, 'DD/MM/YYYY HH24:MI') edate, enddate
from tlh.auctionsession
where id = 1
In the layout tab (HTML form). I write this javascript code in Repeating Section: (it's very simple for example)
<script type="text/javascript">
document.write(##EDATE##);
</script>
It's not woking. Anytime I use the ##EDATE## or ##ENDDATE## in my javascript code, It's not working.
If I put ##EDATE## of ##ENDDATE## in the HTML's body, it's display well.
I am really mad with it.
Do you have any idea? Please help me with it. Thank you very much.
Sorry for my bad English.

// custom vaildation scirpt for entered date being today or a future date;
// date format for the field;
var cDateFormat = "mm/dd/yyyy";
// convert the entered value to a date objecta;
var oEntered = util.scand(cDateFormat, event.value);
// strip down to just the year, month and day
oEntered.setFullYear(oEntered.getFullYear(), oEntered.getMonth(), oEntered.getDate());
// convert todays date to a date object;
oToday = util.scand(cDateFormat, util.printd(cDateFormat, new Date()));
// strip down to just the year, month and day
oToday.setFullYear(oToday.getFullYear(), oToday.getMonth(), oToday.getDate());
// compare the date values
if(oEntered.getTime() < oToday.getTime()) {
// error message date before today's date
app.alert("Date must be today's date or a futuer date!", 1, 0);
// set return code to error status;
event.rc = false;
// validation is assumed to be true unless the event return code value is false;
// end custom validation script;
