Syntax errors with UNPIVOT and JOIN in FROM clause - sql-server

Question

I'm using SQL Server Express (with advanced services), version 10.50.1600.1.
I need to use a UNPIVOT to create multiple rows from a single ROW, and also need to use JOINS, to get fields from master data tables.
I can make 2 working but separate SELECT statements. The first is the UNPIVOT, the second contains the JOINs. But I simply cannot make them work together! When I put the UNPIVOT followed by the JOINs, I'm always getting error 8156 (Column was specified multiple times) or 4104 (The multi-part identifier could not be bound)...
Sample data is in this SQL Fiddle: http://sqlfiddle.com/#!2/452de/1
Here's the sample data
Table TIMESHEET_LINE
PROJECT_ID DATE1 DATE7 HOUR1 HOUR2 HOUR3 HOUR4 HOUR5 HOUR6 HOUR7
16 2011-10-03 2011-10-09 0 0 0,5 0 0 0 0
18 2011-10-03 2011-10-09 0 0 0,01111111 0 0 0 0

The expected output is:

The SQL statement to UNPIVOT the TIMESHEET_LINE table:
SELECT
[USER_ID],
[PROJECT_ID],
[TASK_GROUP_ID],
[TASK_ID],
DATEADD
(
DAY,
CAST( RIGHT([WeekDay],1)
AS int) - 1,
Date1
) As 'Date',
SUM(Hours) AS 'Hours'
FROM [aceproject].[dbo].[TIMESHEET_LINE]
UNPIVOT
(
Hours for [WeekDay] in (HOUR1, HOUR2, HOUR3, HOUR4, HOUR5, HOUR6, HOUR7)
) upvt
WHERE
[USER_ID] = '18'
GROUP BY
[USER_ID],
[PROJECT_ID],
[TASK_GROUP_ID],
[TASK_ID],
[WeekDay],
[Date1]
The SQL Statement to JOIN the tables:
SELECT
TSL.PROJECT_ID,
P.PROJECT_NUMBER,
P.PROJECT_NAME
FROM [TIMESHEET_LINE] AS TSL
INNER JOIN [aceproject].[dbo].[PROJECT] AS P with (nolock) ON P.PROJECT_ID = TSL.PROJECT_ID
I tried to put them together on several ways. First by using JOINs and UNPIVOT in the same SELECT statement:
SELECT
P.PROJECT_NUMBER,
P.PROJECT_NAME,
TSL.[USER_ID],
TSL.[PROJECT_ID],
TSL.[TASK_GROUP_ID],
TSL.[TASK_ID],
DATEADD
(
DAY,
CAST( RIGHT(upvt.[WeekDay],1)
AS int) - 1,
TSL.Date1
) As 'Date',
SUM(upvt.Hours) AS 'Hours'
FROM [TIMESHEET_LINE] AS TSL
INNER JOIN PROJECT AS P with (nolock) ON P.PROJECT_ID = TSL.PROJECT_ID
UNPIVOT
(
Hours for [WeekDay] in (HOUR1, HOUR2, HOUR3, HOUR4, HOUR5, HOUR6, HOUR7)
) upvt
WHERE
TSL.[USER_ID] = '18'
GROUP BY
TSL.[USER_ID],
TSL.[PROJECT_ID],
TSL.[TASK_GROUP_ID],
TSL.[TASK_ID],
upvt.[WeekDay],
TSL.[Date1]
Also tried selecting from the separate statements:
SELECT
Project_ID,
Client_Country,
Project_Create_By,
Resource_Country,
Resource_IPN,
DATEADD
(
DAY,
CAST( RIGHT([WeekDay],1)
AS int) - 1,
Date1
) As 'Date',
Hours AS 'Hours'
FROM
(
SELECT
TSL.[USER_ID],
TSL.[PROJECT_ID],
TSL.[TASK_GROUP_ID],
TSL.[TASK_ID],
TSL.PROJECT_ID AS 'Project_ID',
Left(C.CLIENT_NAME,2) AS 'Client_Country',
LTRIM(PU.USERNAME) AS 'Project_Create_By',
LEFT(UG1.USER_GROUP_NAME,2) AS 'Resource_Country',
LTRIM(U.USERNAME) AS 'Resource_IPN',
TSL.DATE1,
TSL.HOUR1,
TSL.HOUR2,
TSL.HOUR3,
TSL.HOUR4,
TSL.HOUR5,
TSL.HOUR6,
TSL.HOUR7
FROM [aceproject].[dbo].[TIMESHEET_LINE] AS TSL
INNER JOIN [aceproject].[dbo].[PROJECT] AS P with (nolock) ON P.PROJECT_ID = TSL.PROJECT_ID
LEFT JOIN CLIENT AS C with (nolock) ON C.CLIENT_ID = P.CLIENT_ID
LEFT JOIN USERS AS PU with (nolock) ON (PU.COMPANY_ID = P.COMPANY_ID and PU.USER_ID = P.PROJECT_CREATOR_ID)
LEFT JOIN USERS AS U with (nolock) ON U.USER_ID = TSL.USER_ID
LEFT JOIN USER_GROUP AS UG1 with (nolock) ON (UG1.COMPANY_ID = U.COMPANY_ID and UG1.USER_GROUP_ID = U.USER_GROUP_ID)
) d
UNPIVOT
(
Hours for [WeekDay] in (HOUR1, HOUR2, HOUR3, HOUR4, HOUR5, HOUR6, HOUR7)
) upvt
Also tried the opposite, with the UNPIVOT as sub SELECT.
But nothing worked.
Thanks in advance!

Ok, I sorted it out, finally! =)
First you make the JOIN, and then you make a nested select over it:
SELECT TOP 100
TIMESHEET_LINE_ID,
PROJECT_NUMBER,
DATEADD
(
DAY,
CAST( RIGHT([WeekDay],1)
AS int) - 1,
Date1
) As 'Date',
Hours AS 'Hours'
FROM
(
SELECT
P.PROJECT_NUMBER,
TSL.TIMESHEET_LINE_ID,
TSL.DATE1,
TSL.HOUR1,
TSL.HOUR2,
TSL.HOUR3,
TSL.HOUR4,
TSL.HOUR5,
TSL.HOUR6,
TSL.HOUR7
FROM
[aceproject].[dbo].[TIMESHEET_LINE] AS TSL
INNER JOIN PROJECT AS P with (nolock) ON P.PROJECT_ID = TSL.PROJECT_ID
) d
UNPIVOT
(
Hours for [WeekDay] in (HOUR1, HOUR2, HOUR3, HOUR4, HOUR5, HOUR6, HOUR7)
) upvt
