there is some mistake in the script i beleve please suggest and help me out how to fix this problem
the script wht i am using is this
<script type="text/javascript">
function checkdates_baseline(pStartDateItem,pEndDateItem)
var sdate = document.getElementById(pStartDateItem).value;
var edate = document.getElementById(pEndDateItem).value;
var amonths = new Array('JAN','FEB','MAR','APR','MAY','JUN','JUL','AUG','SEP','OCT','NOV','DEC');
var start_date = new Date();
var end_date = new Date();
var start_month = sdate.substring(3,6);
var end_month = edate.substring(3,6);
var nstart_month = 0;
var nend_month = 0;
for(i=0;i<12;i++)
if(amonths == start_month)
nstart_month = i;
if(amonths == end_month)
nstart_month = i;
start_date.setFullYear(sdate.substring(6,10),Number(sdate.substring(3,5))-1,sdate.substring(0,2));
end_date.setFullYear(edate.substring(6,10),Number(edate.substring(3,5))-1,edate.substring(0,2));
var result = (end_date - start_date);
if( result < 0)
alert('The End date must be after the Start Date');
</script>
