Asp.net – Id not binding in controller

Im doing a dontnet website and am having issues with a method in my controller. This is the method in my user controller to allow users to view all their timecards. I tried logging to the terminal and its coming up 0.

   // GET /User/TimeCardLog
    public IActionResult TimeCardLog(int userId)
    {
        Console.WriteLine("The id is " + userId);
        // Get the signed-in user's ID
        var signedInUserId = User.GetSignedInUserId();

        // Determine which user's timecards to retrieve
        int targetUserId;
        if (userId == signedInUserId)
        {
            targetUserId = signedInUserId;
        }
        else
        {
             targetUserId = userId;
        }

        var user = _svc.GetUser(targetUserId);
        if (user is null)
        {
            Alert($"User {targetUserId} Not Found..", AlertType.warning);
            return RedirectToAction(nameof(Index));//TimeCardLog
        }

        var timeCards = _tcSvc.GetTimeCardsByUser(targetUserId);

        var model = new UserTimeCardsViewModel
        {
            User = user,
            TimeCards = timeCards,
        };

        return View(model);
    }

This is my partial view of users belonging to a shop. The edit, reassign and delete user all work for the user intended but when I click on edit timecards I’m getting user 0 not found (so my user is null). I’m now not able to get into the user log either from the personal profile (so the signedinuserid method is not working??)

@model Shop

I initially didn’t have the userId as a parameter but I have added that. I am wanting to see the timecardlog view page which i had seen when I was just using the signedinuser id previously.

I am very new to coding and this is my first real experience creating a website. It might be a simple solution but I can’t seem to figure this out. Any help or ideas would be apprecited!
