passing data from controller to view is showing NAN value

Question

i wish to fetch the count of the row in table using which i wish to restrict the display of the panel inside the page using jquery .

here goes the #dal layer code

int LoanId;
using (TempoDevRM01Entities borrowerDBEntity = new TempoDevRM01Entities())
{
LoanId = borrowerDBEntity.ReferralDetails.Where(x => x.LoanNo == LoanNo).Select(x => x.LoanID).FirstOrDefault();
//LoanId= GetLoanId(LoanNo);
int hardshipcount=borrowerDBEntity.HardshipDiscoveries.Where(x=>x.LoanID==LoanId).Select(x=>x.HardshipDiscoveryID).Count();
return hardshipcount;
}

#view code

var hardshipid =parseInt( @ViewBag.HardshipCount);
if (hardshipid < 1) {
debugger;
$("#panel3").attr("disabled", "disabled");
$("#panel3").css('cursor', 'not-allowed');
}
else {
$("#reviewsubmit").removeAttr("disabled");
$("#panel3").css('cursor', 'POINTER');
}

but it shows NAN value in locals is anythigng wrong with these things?
