better Net display, runtime error '-2147352319(80020101)':

I have made a better NET DISPLAY with Extended price.

but getting this error

after Perform Blind Closeout when RMS syncs Offline backup file.

please download this file.

   var tranType = QSRules.Transaction.TransactionType

   if(tranType != 17)    {    if(tranType != 18)    {    lblTendered.innerText = currencyToString(QSRules.Transaction.TotalTenderIn);    lblChange.innerText = currencyToString(QSRules.Transaction.TotalTenderOut);    }    }

}

I think this part is something wrong.

any idea?
