ForEach Loop Container Mapping Variable From SSIS Package Not Working In SQL-Server StoredProcedure

I have an SSIS package that uses a ForEach Loop Container to enumerate Excel Files in a dir. I also have a Task Flow that inserts data from those Excel files into SQL-Server.

Im trying to insert the file names into a column into the same table in SQL-Server by using a mapping variable in my StoredProcedure.

Im having trouble with my MappingVariable at the end of the script with red squigglies. The following is my StoredProcedure script.

CREATE PROCEDURE [dbo].[Insert_F_STG_v2]
    -- Add the parameters for the stored procedure here


    @Hrs float,
    @Type nvarchar(100),
    @SN nvarchar(100),
    @Op nvarchar(100),
    @[USER::CurrentFileName]  


AS
BEGIN

SET NOCOUNT ON;




    INSERT INTO [CRM_RC].[dbo].[F_StgTbl]
           (
            [Hrs],
            [Type],
            [SN],
            [Op],
            [Report_Date]
            )
    VALUES
           (

            @Hrs ,
            @Type,
            @SN,
            @Op,
            @[USER::CurrentFileName]
           )

END

The last @[USER::CurrentFileName] in the Values block at the bottom of the script is the one giving me issues.

The following is the error:

Msg 102, Level 15, State 1, Procedure Insert_F_STG_v2, Line 95
Incorrect syntax near 'USER::CurrentFileName'.
