Hi

I have a requirement wherein I would want to get the orders which got delayed by 10 days on shipment.So to get the same I have written a expression like this

count({<shipmentdate={>=$(=date((orderdate+5),'DD/MM/YYYY')}>}orderid)a

But it is not giving me the desired results.So can anyone please help me on the same

=count({<shipmentdate={">=$(=date((orderdate+5),'DD/MM/YYYY')<=$(=date((orderdate+10),'DD/MM/YYYY')"}>}orderid)
