Joining with sub query not working

Question

Hi
I am new with these complex queries. I am trying to join a sub query to a query as below;
SELECT Events1.InvoiceBatch AS BatchNo, Events1.InvoiceBatchDate AS BatchDate, tblClients.Company, tblClients.ID AS ClientID, COUNT(Events1.ID) AS Invoices,
COUNT(*) - COUNT(Events1.InvoicePrintDate) AS E, Events1.InvoiceBatchFromDate AS BatchFrom, Events1.InvoiceBatchToDate AS BatchTo, (SELECT EventID, SUM(Total) FROM tblStaffBookings AS StaffBookings WHERE StaffBookings.EventID = Events1.ID GROUP BY EventID) AS Total
FROM tblEvents AS Events1 LEFT OUTER JOIN
tblClients ON Events1.ClientID = tblClients.ID
WHERE (Events1.FactoringExportDate IS NULL) OR (Events1.AccountsExportDate IS NULL) OR (Events1.InvoiceSentDate IS NULL)
GROUP BY Events1.InvoiceBatch, Events1.InvoiceBatchDate, tblClients.Company, tblClients.ID, Events1.InvoiceBatchFromDate, Events1.InvoiceBatchToDate
HAVING (Events1.InvoiceBatch = 5212)
ORDER BY tblClients.Company
I am getting these two errors;
Msg 8120, Level 16, State 1, Line 2
Column 'tblEvents.ID' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
Msg 116, Level 16, State 1, Line 2
Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.
What am I missing?
Thanks
Regards

SELECT Events1.InvoiceBatch AS BatchNo, Events1.InvoiceBatchDate AS BatchDate, tblClients.Company, tblClients.ID AS ClientID, COUNT(Events1.ID) AS Invoices,
COUNT(*) - COUNT(Events1.InvoicePrintDate) AS E, Events1.InvoiceBatchFromDate AS BatchFrom, Events1.InvoiceBatchToDate AS BatchTo,Total
FROM tblEvents AS Events1 LEFT OUTER JOIN
tblClients ON Events1.ClientID = tblClients.ID
LEFT OUTER JOIN (SELECT EventID, SUM(Total) AS Total FROM tblStaffBookings AS StaffBookings WHERE StaffBookings.EventID = Events1.ID GROUP BY EventID) sb
ON sb.EventID = Events1.ID
WHERE (Events1.FactoringExportDate IS NULL) OR (Events1.AccountsExportDate IS NULL) OR (Events1.InvoiceSentDate IS NULL)
GROUP BY Events1.InvoiceBatch, Events1.InvoiceBatchDate, tblClients.Company, tblClients.ID, Events1.InvoiceBatchFromDate, Events1.InvoiceBatchToDate,Total
HAVING (Events1.InvoiceBatch = 5212)
ORDER BY tblClients.Company

Msg 4104, Level 16, State 1, Line 5
The multi-part identifier "Events1.ID" could not be bound.
on
LEFT OUTER JOIN (SELECT EventID, SUM(Total) AS Total FROM tblStaffBookings AS StaffBookings WHERE StaffBookings.EventID = Events1.ID GROUP BY EventID) sb
