Error in form--expected class, delegate, enum, interface, or struct

 I am using Microsoft Visual C# to try to find
isolate an error.  It is highlighting "void" in the first line, and the
following error comes up:

Expected class, delegate, enum, interface, or struct

What does that mean and how can I fix it?
 
This is the code:  Thanks!

protected void status_SelectedIndexChanged(object sender, System.EventArgs e)
{

if (statusAns.SelectedValue == "status_guest") {
RequiredFieldValidator4.enabled = true;
}
else {
RequiredFieldValidator4.enabled = false;
}

}


Status:*
"status"
OnSelectedIndexChanged="status_SelectedIndexChanged"
...
