Syntax Error - Order

I am trying to merge output from 3 selection processes. Here is the code that I am using and then I will show the error that I am receiving when trying to execute.

select COALESCE(a.[Class],b.[Class],c.[Class])            AS [Class],
COALESCE(a.[Material],b.[Material],d.[Material])          AS [Material],
COALESCE(a.[Description],b.[Description],c.[Description]) AS [Description],
COALESCE(a.[A],0) + coalesce(b.[A],0) + coalesce(c.[A],0) AS [On Hand],
COALESCE(a.[B],0) + coalesce(b.[B],0) + coalesce(c.[B],0) AS [On Order],
COALESCE(a.[C],0) + coalesce(b.[C],0) + coalesce(c.[C],0) AS [Picked],
