How to pass parameter in stored procedure execution for OLE DB source in SSIS

I'm having problems when executing a stored procedure in an OLE DB source in SSIS,

I have set the OLE DB source to SQL command and put the following:

This is the code for the SQL command text:

exec timesheet_r12..TIME_lynx_extract ?,?,?,?,?,?,?,?,?,?,?,?,?

WITH RESULT SETS (
(
worker_reference    NVarchar(50),
placement_reference  NVarchar(10),
worker_name NVarchar(50),
job_title   NVarchar(100),
authorising_line_manager    NVarchar(100),
timesheet_date  datetime,
company_agent_name  NVarchar(100),
type_of_worker  NVarchar(100),
week_number NVarchar(100),
hours_worked    NVarchar(100),
rate_description    NVarchar(100),
rate_per_hour   NVarchar(10),
job NVarchar(100),
work_stage  NVarchar(100),
project_name    NVarchar(100),
location NVarchar(100)
)
)

The first 2 parameters that I need to send are @startweek and @endweek for these,I need to find out how to send the last friday as "@endweek" and the friday of 4 weeks ago as "@startweek" (4 fridays before).

if I want to execute with hard coded @startweek and @endweek the Stored Procedure in the Database, I can do it with the following command:

exec timesheet_r12..TIME_lynx_extract
     '19 Jul 2018', 
     '16 Aug 2019',
     null,null,null,null,null,null,null,null,null,null,null

this is the error I'm getting when executing the package in SSIS:

SSIS package "C:\Users\AGUIRRG2\source\repos\Integration Services Project3\Integration Services Project3\Package.dtsx" starting.

Warning: 0x80019002 at Package: SSIS Warning Code DTS_W_MAXIMUMERRORCOUNTREACHED.  The Execution method succeeded, but the number of errors raised (2) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.
SSIS package "C:\Users\AGUIRRG2\source\repos\Integration Services Project3\Integration Services Project3\Package.dtsx" finished: Failure.
The program '[24756] DtsDebugHost.exe: DTS' has exited with code 0 (0x0).

So right now what I would need is to know how to pass the parameters to SSIS, and how to make them dynamic, @startweek and @endweek can be calculated.

Thank you.
