I'm not sure why you are getting that message. Did you modify the code in
any way? Is it highlighting a line of code when it displays the message? If
so, which line. If not, put a breakpoint on the first line of my code (click
the left hand border and a red dot will appear along with the line being
highlighted in red indicating the breakpoint is set); then change the value
in B1. You will be taken back to the code window and the line with the
breakpoint will be highlighted in yellow. Pressing F8 will execute the line
of code and advance the yellow highlight to the next executable line. Keep
pressing F8 until the message appears. Which line was the last one
highlighted in yellow before the error appeared?

This seemed to work right away, but now I'm getting an "argument not
optional" message when I put a number. What could this mean?

Okay, the 'start at Row 3' was a mistype then. By the way, you originally
said B1 would have the number in it, but now are saying A1. No problem,
I'll
use A1 in my example. Give this a try and see if it does what you want.
Right-click the tab on the worksheet where you want to have this
functionality and select View Code from the popup menu that appears. This
will take you into the VBA editor and present an already opened code
window
to you. Copy/Paste the following into that code window...

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$B$1" Then
Range("2:" & Rows.Count).EntireRow.Hidden = False
Range(CStr(2 + 2 * Range("B1").Value) & ":" & _
Rows.Count).EntireRow.Hidden = True
End If
End Sub

Now, go back to the worksheet and type different numbers into A1 to see
if
the code is doing what you want. You can put a drop-down list into A1 if
you
want... it will not matter to the code how the number gets into the cell.

New2Macros:

Sorry I'm not being clear enough. Say in cell A1 you want to enter the
number of rows being shown in the spreadsheet. A1 should always be
shown,
of
course, and each number entered in A1 will show double the amount of
rows
below. Each row starting with A2 will have information entered
previously,
so we are just displaying, or hiding those rows below. For instance:
if
I
want only 2 rows displaying below, I would enter a "1" in cell A1. If
I
want
10 rows to show, I would enter "5" in A1, and so on. A1 probably will
have a
pull down.

I don't completely understand your criteria. From your example, if the
user
picks 2, how do you know to start showing rows at Row 3? And if you
hide
everything except for Rows 3 through 6, then B1 will be hidden and you
won't
be able to change the number in it again without manually unhiding it.
Can
you give us more details on how you want this functionality to work
(keep
in
mind that no one here has any idea what you want to do, so you have to
tell
us).

That is close. What I need is that you can choose from 1 to 35
(maybe
in
a
pull down), and have it show the twice that many rows. So if you
pick
2
it
would show rows 3 through 6 and hide all the other pre-populated
rows.

Also when I plugged in that macro I'm getting an error '1004'.
"Unable
to
set the hidden property of the range class."

I need to use a single cell to show/hide other rows. For instance
if
you
put
a "6" in cell B1 it would show the next 12 rows and hide the rest.
If
you
put in a "10" it would show the next 20 rows and hide the rest,
etc.

I'm new to writing macros, sorry!
