CS0116 and CS0103 Error, cant create an IAction?

EDIT: Issue was a buried ‘}’ in my code, apologies for all confusion.

I do not understand why only one specific IAction is returning this error, I have implemented the other actions without any similar error.
I am getting errors of CS0116 and CS0103.
[]
I have defined my viewModel the same manner as other actions, I am attaching the code for the ViewModel and the Detail action below.
The class =>

namespace Paycompute.Controllers

{
    public class EmployeeController : Controller
    {
        private readonly IEmployeeService _employeeService;
        private readonly IWebHostEnvironment _hostingEnvironment;

        public EmployeeController(IEmployeeService employeeService, IWebHostEnvironment hostingEnvironment)

The action =>

    [HttpGet]
public IActionResult Detail(int id)
{
    var employee = _employeeService.GetById(id);
    if (employee == null)
    {
        return NotFound();
    }
    EmployeeDetailViewModel model = new EmployeeDetailViewModel()
    {
        Id = employee.Id,
        EmployeeNo = employee.EmployeeNo,
        ImageUrl = employee.ImageUrl,
        FullName = employee.FullName,
        Gender = employee.Gender,
        Designation = employee.Designation,
        City = employee.City,
        DateJoined = employee.DateJoined,
        SocialSecurityNo = employee.SocialSecurityNo,
        Phone = employee.Phone,
        Email = employee.Email,
        PaymentMethod = employee.PaymentMethod,
        StudentLoan = employee.StudentLoan,
        UnionMember = employee.UnionMember,
        Address = employee.Address,
        City = employee.City,
        ImageUrl = employee.ImageUrl,
        Postcode = employee.Postcode,
    };
    return View(model);
}

The view model =>

using Paycompute.Entity;

namespace Paycompute.Models
{
    public class EmployeeDetailViewModel
    {
        public string FullName { get; set; }
        public int Id { get; set; }
        public string EmployeeNo { get; set; }
        public string Gender { get; set; }
        public string ImageUrl { get; set; }
        public DateTime DOB { get; set; }
        public DateTime DateJoined { get; set; }
        public string Phone { get; set; }
        public string Designation { get; set; }
        public string Email { get; set; }
        public string SocialSecurityNo { get; set; }
        public PaymentMethod PaymentMethod { get; set; }
        public StudentLoan StudentLoan { get; set; }
        public UnionMember UnionMember { get; set; }
        public string Address { get; set; }
        public string City { get; set; }
        public string Postcode { get; set; }
    }
}

EDIT: Upon reviewing my question, I realize from the comments that I have not included the error message, my apologies I am new to the forum.
The messages were:

Error CS0116 A namespace cannot directly contain members such as fields, methods or statements Paycompute C:\Projects\PaycomputeApp\Paycompute\Controllers\EmployeeController.cs 169 Active

Error CS0103 The name ‘_employeeService’ does not exist in the current context Paycompute C:\Projects\PaycomputeApp\Paycompute\Controllers\EmployeeController.cs 171 Active

>Solution :

CS0116 "A namespace cannot directly contain members such as fields or methods." suggests that you’ve forgotten to put your method in a type, i.e.

namespace SomeNamespace 
{
    public class SomeTypeHere // << added - perhaps also : Controller
    {
        [HttpGet]
        public IActionResult Detail(int id)
        {

CS0103 "The name ‘identifier’ does not exist in the current context" is probably related, i.e. because there’s nowhere for NotFound(), View(model) etc to come from.
