Judi;
Not that this is much of an answer but I copied your code directly and it works perfectly for me
(Excel '03 on Xp).
Try adding these statements to the beginning of the module (before the "Sub" statement).

Dim x as long
Dim y as integer
Dim z as long

Sounds like you options are set to "Require Variable Declaration" (Tools-Options-Editor-Code
Settings")
This means that any variable you use must be declared (done via "Dim" statement).

I am trying to work through the online training provided by Microsoft about
Excel 2003 and I have run into an issue with the Macro lesson.

Following the instructions exactly, I have entered this macro in to a module
in the spreadsheet:

Sub CountRows()

x = ActiveCell.Row
y = ActiveCell.Column
z = 0

Do While Cells(x, y).Value < ""
x = x + 1
z = z + 1
Loop

MsgBox "There are " & z & " rows in the current range."

End Sub

When I try to run the macro, it tell me that variable x is undefined. I
tried going into the spreadsheet and placing the focus where they said and
running it from there, but I get the same message.

Please help me understand what I need to do to fix this. I am doing the
training so that I can understand this, but if the training is wrong, how am
I supposed to learn?

Feel free to talk to me like a child, I'm completely new to VBA.

Thank you to all who offer help.
