The user must select a date from the dropdown.
I need to display an alert message "error" when the user selects
jul 21, 2008 in the dropdown and the date today is aug 21, 2008
or the when the user selects the date that is less than the date today.
the user must select a date that is greater than the date today.
could you please help me?

Try to have this:

<script type="text/javascript">
window.onload=function(){
document.getElementById('trig').onclick=function(){
var date=new Date(),month=date.getMonth(),day=date.getDate(),year=date.getFullYear(),
monthOpt=document.getElementById('month'), // id for month dropdown
dayOpt=document.getElementById('date'), // id for days dropdown
yearOpt=document.getElementById('year') ; // id for year dropdown.
if(monthOpt.value<=(month+1)&&dayOpt.value<=day&&yearOpt.value<=year)
alert('Error. The date today is: '+monthOpt.options[month].text+' '+day+' '+year+'.');
}}
</script>
<input type="button" value="Get Marvelled" id="trig">

See if it works.

thanks, when the alert says "error", the date entered by the user will not insert into the database.

It was not mentioned in the first thread you have, and I can't see anything in the 1st post that there was a connection in the DB.

Up the related codes, but I should inform you in advance that server-side is not my forte, I may/may not help.

When the user press the ok or close the alert, the date entered by the user will not insert into the database. Isn't possible in javascript?

Oh, my bad. I misread your post. Try to add highlighted instead:

<script type="text/javascript">
window.onload=function(){
document.getElementById('trig').onclick=function(){
var date=new Date(),month=date.getMonth(),day=date.getDate(),year=date.getFullYear(),
monthOpt=document.getElementById('month'), // id for month dropdown
dayOpt=document.getElementById('date'), // id for days dropdown
yearOpt=document.getElementById('year') ; // id for year dropdown.
if(monthOpt.value<=(month+1)&&dayOpt.value<=day&&yearOpt.value<=year){
alert('Error. The date today is: '+monthOpt.options[month].text+' '+day+' '+year+'.');
return false;}
}}
</script>
