Data Report Issue

Friends,

I had designed an application.

I want Report like as follows using Data Grid.

TITLE
Date: Page 1 of 1

Region : North

Port Name Quantity FOB UP
XYZ 100 100 1
KLM 200 200 1
ABC 650 650 1
FGH 722 72000 100
Region Total 1672 72950

Region : South

Port Name Quantity FOB UP
KLM 100 100 1
UVW 200 200 1
RST 650 650 1
IJK 722 72000 100
Region Total 1672 72950

Grand Total 3344 145900

My Query:

select ROW_NUMBER()OVER (ORDER BY er.Port_Name) AS Row,er.Port_name,pm.Region,
sum(Quantity) Quantity,sum(Fob) Fob,convert(numeric(18,2),sum(Fob)/sum(Quantity)) Unitprice
from Exporter_Returns er join Exporter_Master em on er.exporter_id=em.exporter_id join
port_master pm on pm.port_name=er.port_name where returns_month
between '2010-01-01' and '2013-08-01' and quantity!=0 group by er.Port_Name,pm.Region

Please find my Report Design. But I am unable to grouping. There is error message.
