I am an extreme beginner here. This is the code for my model:

namespace Portal2.Models
{
    using System;
    using System.Collections.Generic;
    
    public partial class V_Routings
    {
        public string Job { get; set; }
        public string Customer { get; set; }
        public string Rev { get; set; }
        public string Part_Number { get; set; }
        public string Description { get; set; }
        public string Status { get; set; }
        public int Promised_Quantity { get; set; }
        public string Order_Unit { get; set; }
        public System.DateTime Promised_Date { get; set; }
        public string Comment { get; set; }
        public string Work_Center { get; set; }
        public string Expr1 { get; set; }
        public Nullable<int> Remaining_Quantity { get; set; }
    }
}

I am trying to put the Work_Center value in the text area.
<p>@Model.Work_Center</p>

Thanks for your quick response. I had already tried that. I am getting this:

Compilation Error

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS1061: 'System.Collections.Generic.List<Portal2.Models.V_Routings>' does not contain a definition for 'Work_Center' and no extension method 'Work_Center' accepting a first argument of type 'System.Collections.Generic.List<Portal2.Models.V_Routings>' could be found (are you missing a using directive or an assembly reference?)

Source Error:

I didn't realize that you specify a List<Portal2.Models.V_Routings>

Suppose the Work_Center is the same in all items returned.
<p>@Model[0].Work_Center</p>

A more maintanable code
   public partial class V_Routings
   {
        public string Work_Center { get; set; }
       // Put other attibutes here ...

        public List<RoutingItems> Items { get; set; }
   }

    public class RoutingItems
    {
        public string Job { get; set; }
        public string Customer { get; set; }
        public string Rev { get; set; }
        public string Part_Number { get; set; }
        public string Description { get; set; }

        public int Promised_Quantity { get; set; }
        public string Order_Unit { get; set; }
        public System.DateTime Promised_Date { get; set; }
        public string Comment { get; set; }
        public string Expr1 { get; set; }
        public Nullable<int> Remaining_Quantity { get; set; }

The table right below that is working and filling with data from the same model.

        @foreach (var item in Model)
            {
                var cssName = "";
                if (item.Promised_Date < DateTime.Now.Date)
                { cssName = "passed"; }
                else if (item.Promised_Date == DateTime.Now.Date)
                { cssName = "current"; }
                <tr class="@cssName">
                    <td>@item.Promised_Date.ToString("MM/dd/yyyy")</td>
                    <td><a href="/routing/jobdetails/@item.Job">@item.Job</a></td>
                    <td>@item.Customer</td>
                    <td>@item.Part_Number</td>
                    <td>@item.Description</td>
                    <td>@item.Rev</td>
                    <td>@item.Promised_Quantity</td>
                    <td>@item.Remaining_Quantity</td>
                    <td>@item.Status</td>
                    <td>@item.Comment</td>
                </tr>
            }
    </tbody>

This works on my computer VS2013 + framework 4.5 + MVC5

Also you should tag the string "Routing"
<p>@Model[0].Work_Center <span>Routing</span></p>
