Update Query Access 2007 Group into one row - sql

Question

I'm playing around with access and vba. I'm struggleing to update and to group rows from tblLoadingListItems into tblLoadSummary using the query below
UPDATE tblLoadSummary INNER JOIN tblLoadingListItems ON (tblLoadSummary.salesno = tblLoadingListItems.salesno) AND (tblLoadSummary.loadnolink = tblLoadingListItems.loadnolink) SET tblLoadSummary.[Cust O/N] = [tblLoadingListItems].[Cust O/N], tblLoadSummary.traderid = [tblLoadingListItems].[traderid], tblLoadSummary.street = [tblLoadingListItems].[street], tblLoadSummary.[zone] = [tblLoadingListItems].[zone], tblLoadSummary.salesno = [tblLoadingListItems].[salesno], tblLoadSummary.[Customer Ref] = [tblLoadingListItems].[Customer Ref], tblLoadSummary.DeliveryAddress = [tblLoadingListItems].[DeliveryAddress], tblLoadSummary.Postcode = [tblLoadingListItems].[Postcode], tblLoadSummary.SumOfnoofpacks = Sum([tblLoadingListItems].[packs1]), tblLoadSummary.SumOfnoofboxes = Sum([tblLoadingListItems].[noofboxes]), tblLoadSummary.contact = [tblLoadingListItems].[contact], tblLoadSummary.telephone = [tblLoadingListItems].[telephone], tblLoadSummary.fax = [tblLoadingListItems].[fax], tblLoadSummary.email =
[tblLoadingListItems].[email], tblLoadSummary.deliverycontact = [tblLoadingListItems].[deliverycontact], tblLoadSummary.deliverytelephone = [tblLoadingListItems].[deliverytelephone], tblLoadSummary.deliveryfax = [tblLoadingListItems].[deliveryfax], tblLoadSummary.deliveryemail = [tblLoadingListItems].[deliveryemail], tblLoadSummary.acknowaddress = [tblLoadingListItems].[acknowaddress]
WHERE (((tblLoadSummary.salesno)="SM-100118") AND ((tblLoadSummary.loadnolink)=32232))
If i show datasheet view i get two rows returned, Im trying to group these rows into one.
When i try to add a GROUP BY after the WHERE i get syntax errors missing operators for all my fields.
Can you someone point me in the right direction?

I am not sure with access but starting update like this and maybe its wrong :
Update tblLoadSummary inner join...
try it like this
update t set .... from tblLoadSummary t inner join tblLoadSummary s on ...
this is the full query
UPDATE t-- tblLoadSummary
SET t.CustO/N = s.CustO/N,
t.traderid = s.traderid,
t.street = s.street,
t.zone = s.zone,
t.salesno = s.salesno,
t.CustomerRef = s.Customer Ref,
t.DeliveryAddress = s.DeliveryAddress,
t.Postcode = s.Postcode,
t.SumOfnoofpacks = Sum(s.packs1),
t.SumOfnoofboxes = Sum(s.noofboxes),
t.contact = s.contact,
t.telephone = s.telephone,
t.fax = s.fax,
t.email = s.email,
t.deliverycontact = s.deliverycontact,
t.deliverytelephone = s.deliverytelephone,
t.deliveryfax = s.deliveryfax,
t.deliveryemail = s.deliveryemail,
t.acknowaddress = s.acknowaddress
from tblLoadSummary as t
INNER JOIN tblLoadingListItems as s ON
(t.salesno = s.salesno) AND (t.loadnolink = s.loadnolink)
WHERE (((t.salesno) = "SM-100118") AND
((t.loadnolink) = 32232))
