John,

I've tried what you suggest and it produces an error
right off ... here's what I'm doing (below) What is
wrong?

Sub upDateHis1()

booknm = Workbooks("hilowwork book.xls").Worksheets
("UpdateInfo")
lwrLimit = Range("lwr").Row + 1
uprLimit = Range("eend").Row - 1
lgOpnHi = Range("OpnHi").Column
lgStokNow = Range("StokNow").Column
lgStokhi = lgStokNow + 1


For rwIndex = lwrLimit To uprLimit

'This sets High Value of Option
With Worksheets("UpdateInfo").Cells(rwIndex,
lgOpnHi)
If .Value _
< Worksheets("UpdateInfo").Cells(rwIndex,
lgOpnHi - 1).Value _
Then .Value = Worksheets("UpdateInfo").Cells
(rwIndex, lgOpnHi - 1).Value
If .Value * 0.75 _
Worksheets("UpdateInfo").Cells(rwIndex,
lgOpnHi - 1).Value _
Then Worksheets("UpdateInfo").Cells
(rwIndex, 4).Value _
= "SELL"
End With
'This sets high value of Stock
If Worksheets("UpdateInfo").Cells(rwIndex,
lgStokNow).Value _
Worksheets("UpdateInfo").Cells(rwIndex,
lgStokhi).Value _
Then
Worksheets("UpdateInfo").Cells(rwIndex,
lgStokhi).Value _
= Worksheets("UpdateInfo").Cells(rwIndex,
lgStokNow).Value

Worksheets("UpdateInfo").Cells(rwIndex,
lgStokhi + 1).Value _
= Now
End If

Next rwIndex

rePeater

End Sub

You can refer to cells in non-active workbooks by fully
qualifying the references. Something like:

x = Workbooks("A.xls").Worksheets("Sheet1").Range
("A1").Value

If you need to make lots of references to the same
object, use the following:

With Workbooks("A.xls").Worksheets("Sheet1")
x = .Range("A1").Value
.Range("A2").Value = x

End With

Is there any way to get a macro to execute on a
workbook
which is open, but not active?

I have a macro in a certain workbook (call it "A")which
repeats automatically but if I I open another workbook,
say "B", then the macro produces an error because it
doesn't find the data it needs in the active worksheet
if
I'm working in "B".

I've added the following code to the start of my macro

Workbooks("hilowwork book.xls").Activate
Worksheets("UpdateInfo").Activate

and the macro runs fine but it causes the sheet to
become
active and it interrupts the work I may be doing in
workbook "B".

Is there some way I can feed the macro the information
of
the workbook name and sheet name that it is to operate
on
so that it does this in the background and still allows
me to continue working in workbook "B" without
interruption?
