I AM KEYING IN THE CODE FOR BEGINNING VISUAL BASIC DIRECTLY FROM THE AUTHORS EXAMPLE. I HAVE DONE IT SEVERAL TIMES I KEEP GETTING THE SAME ERRORS. IS THE CODE WRONG FROM THE AUTHORS.? SEE THE CODE BELOW.
CODE
Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'DECLARE VARIABLE
Dim DBLAREA As Double

'CALCULATE THE AREA FOR A CIRCLE WITH A RADIUS OF 100
DBLAREA = CalculateAreaFromRadius(100)

'DISPLAY THE RESULTS
MessageBox.Show(DBLAREA.ToString, "AREA OF 100")
'CALCULATEAREAFROM RADIUS - FIND THE AREA OF A CIRCLE
'CALCULATEAREAFROM RADIUS - FIND THE AREA OF A CIRCLE


End Sub
Private Sub SayHello()
'display a message box
MessageBox.Show("I Have Changed it!", "three buttons")


End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
'call your method
SayHello()

End Sub

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
'call your method
SayHello()

End Sub
End Class

'CalculateAreaFromRadius -find the area of a circle
Private Function CalculateAreaFromRadius(ByVal radius As Double) As Double
'declare variables
Dim dblRadiusSquared As Double
Dim dblResult As Double

'square the radius
dblRadiusSquared = radius * radius

'multiply it by pi
dblResult = dblRadiusSquared * Math.PI
'return the result
Return dblResult
End Function
/CODE
Error 1 Name 'CalculateAreaFromRadius' is not declared.
Error 2 Statement is not valid in a namespace.

I DON'T UNDERSTAND WHAT THE PROBLEM IS.
HELP

You have your *BEFORE* your function!

END CLASS should be the very very very last thing in the file.

DEAR Old Pedant: I KNOW THIS IS A VERY BASIC ERROR, BUT I AM JUST STARTING AND THE BOOK HAS NOT COVERED THE INFORMATION YOU SENT ME. THEY JUST STATED TO ENTER THE CODE BUT DIDN'T STATE EXACTLY WHERE I SHOULD PUT THE CODE SO I JUST PUT IN AT THE BOTTOM. YOUR ANSWER FIXED THE PROBLEM AND IT WAS IMMEDIATELY OBVIOUS. I HOPE THE BOOK DOESN'T HAVE MANY OF THESE KIND OF OMISSIONS.
THANKS
