[SOLVED] Problem using global variables at static functions

See more:

C#

ASP.NET

I know this a very newbie question... so lets see:

I define global variables:

string strConn;
     SqlCommand cmd;
     SqlConnection conn;

and then on page_load:

strConn = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["ConnectionString1"].ConnectionString;
       conn = new System.Data.SqlClient.SqlConnection(strConn);
        conn.Open();

The problem is with public static functions I cant do:

cmd = new SqlCommand("sql query..", conn);

because I get: at (cmd and conn)

An object reference is required for the nonstatic field, method, or property

how can I solve this problem ?

SOLVED:

Yes I know it was a newbie question (altough I need more than one hour to know how to do it).

public static SqlCommand cmd;
     public static SqlConnection conn;
