You haven't even declared the message variable anywhere.

Solution 1

C#

string message=cmd.Parameters["@ERROR"].Value.ToString(); // declare type for message
lblErrorMsg.Text = message;  // now you can use it..

You have not declared a type for message, but even if you did, it will only exist inside your if block. You need to declare it at the top of the event block like:

C#

protected void btnsubmit_Click(object sender, EventArgs e)
{
    string message = ""; // set default message text here
    if (txtpwd.Text == txtcnmpwd.Text)
    {
// ...

Solution 3

C#

protected void btnsubmit_Click(object sender, EventArgs e)
{
    string message = ""; //Default value. You can make it "" else string.empty

    if (txtpwd.Text == txtcnmpwd.Text)
    {
       message=cmd.Parameters["@ERROR"].Value.ToString();

      if(message!= null) // check here if message is returning some values.
      {
         lblErrorMsg.Text = message;
      }
    } // Missing } added
} // Missing } added

Hope this helps. :)
