Sorry, forgot to add the group by statement

so it should be like this:

, SUM(b.cost) AS Sum_of_Cost
, SUM(b.estimate_cost) AS Sum_of_Estimated_Cost
, SUM(c.quantity) AS Sum_of_Quantity
, SUM(c.estimate_quantity) AS Sum_of_Estimated_Quantity
FROM Projects a
LEFT JOIN Cost b ON a.project_pk = b.project_pk
LEFT JOIN Quantity c ON a.project_pk = c.project_pk
GROUP BY a.Project_PK
