Query Works in Query Designer - Doesn't Work in Report

Question

I have a report that runs just fine in the Query Designer, but for some reason does not run when I run the actual report. Here is the query in question:
SELECT
{[Measures].[Employee Hours]} ON COLUMNS
,NON EMPTY
[Employee].[Employee Full Name].[Employee Full Name].ALLMEMBERS*
[Employee].[Employee Discipline].[Employee Discipline].ALLMEMBERS*
[Employee].[Employee Department].[Employee Department].ALLMEMBERS*
[Employee Hours Time Category].[Utilization Category].[Utilization Category].ALLMEMBERS*
[Employee Hours Time Category].[Time Category].[Time Category].ALLMEMBERS*
[Project].[Client].[Client].ALLMEMBERS*
[Time].[Year].[Year].ALLMEMBERS*
[Time].[Month].[Month].ALLMEMBERS*
[Time].[Formatted Week].[Formatted Week].ALLMEMBERS
DIMENSION PROPERTIES
MEMBER_CAPTION
,MEMBER_UNIQUE_NAME
ON ROWS
FROM
SELECT
LastPeriods (7, StrToMember
(@SelectedWeek
,CONSTRAINED
)) ON COLUMNS
FROM
SELECT
StrToSet
(@Department
,CONSTRAINED
) ON COLUMNS
FROM
SELECT
StrToSet
(@Disciplines
,CONSTRAINED
) ON COLUMNS
FROM [OLSON BI]
CELL PROPERTIES
VALUE
,BACK_COLOR
,FORE_COLOR
,FORMATTED_VALUE
,FORMAT_STRING
,FONT_NAME
,FONT_SIZE
,FONT_FLAGS;
The result set is below:
When I try to run the actual report, I get an error on the parameter being passed in. I'm passing in a date that is formatted as a varchar as you can see from the screen shot below:
Not sure what's going on here, but any insight would be appreciated!
Thank you!

Hi ansonee,
Because the query execute successfully in the query designer, so the issue can be caused by the parameter in the report.
If you have a string such as "@string" somewhere in a query, and it is not mapped correctly in the reporting services parameter section, it will send that string directly to the provider with no substitution of parameter values. This will cause
an error like the above. Please check carefully. Here has a thread that is similar to yours, please see:
SSRS error in MDX expression syntax is incorrect
SSRS failing when parameter value contain SPACE in between
Hope this helps.
