Question : Procedure or function has too many arguments specified.

Hi,
I execute 2 procedures from Windows form in vb.net. After each is executed I should update my status table in databes with information that the same was exec OK (by exec Execution_flag sp) . For the first stored proc from the list everithing is OK (the same executed and the status table updated) . When I try to execute the second sp from the list the same is executed OK but when I try to update my status table (by executing "Execution_flag" sp) I receive this error message (as in Title).
Please help me to solve the problem...
My code is below (breaks in line 26). Variable needed for execution of Execution_flag is forwarded OK (the same represents stored porcedure name which last was executed).
Also, in addition please find my stored proc "Execution_flag":
ALTER PROCEDURE [dbo].[Execution_flag]
@stor_proc_name varchar(100)
AS
INSERT INTO SP_EXECUTION_TIMESTAMP
SELECT a.Name,a.object_id,a.type,a.type_desc,b.last_execution_time,b.last_worker_time as Execution_duration,'Y' as Execution_flag,
HOST_NAME() AS HostName, SUSER_NAME() LoggedInUser
FROM sys.objects as a JOIN sys.dm_exec_procedure_stats as b ON a.object_id = b.object_id
WHERE a.name = @stor_proc_name
Thank you...
