Pass parameters from ASP.NET to stored procedure in SQL server and get data back from the stored procedure and view it on a gridview

I want to pass parameters from asp.net to my stored procedure. The parameters would be the value selected by the user from the dropdownlists and then get data back from the stored procedure and display on a Gridview in asp.net when the user clicks the submit button on the webpage. An exception pops up by the Fill method when I try to debug it saying I need to pass parameters. The exception is copied below.

System.Data.SqlClient.SqlException: 'Procedure or function 'Submit' expects parameter '@Address', which was not supplied.'

Below is my stored procedure

USE [Database]
    GO
    
    SET ANSI_NULLS ON
    GO
    SET QUOTED_IDENTIFIER ON
    GO
    ALTER procedure [Submit]
    @Address varchar(12),
    @Number varchar(5),
    @Name varchar(24),
    @Type varchar(3)
    as 
    begin
        select a.*, b.*
        from Employee as a
        inner join Department as b
        on a.Number = b.Number
        where a.Address = @Address and a.Number = @Number and a.name = @Name and b.Type 
        = @Type 
    end

Below is my .cs code

protected void Button1_Click1(object sender, EventArgs e)
            {
                con.Open();
                string s = "Submit";
                SqlCommand cmd = new SqlCommand();
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.CommandText = "Submit";
                cmd.Parameters.Add("@Address", SqlDbType.VarChar).Value = DropDownList5.SelectedItem.Value;
                cmd.Parameters.Add("@Number", SqlDbType.VarChar).Value = DropDownList2.SelectedItem.Value;
                cmd.Parameters.Add("@Name", SqlDbType.VarChar).Value = DropDownList3.SelectedItem.Value;
                cmd.Parameters.Add("@Type", SqlDbType.VarChar).Value = DropDownList4.SelectedItem.Value;
                SqlDataAdapter da = new SqlDataAdapter(s, con);
                DataSet ds = new DataSet();
                da.Fill(ds);
    
                GridView1.DataSource = ds;
                GridView1.DataBind();
                con.Close();
            }
