...Random Numbers not Random
When I create random numbers for an application with the following code, they
do not appear to be truely random.
Me.RandomNumber = Int(9 * Rnd + 1) ' Random Number 1-9
If I have two users setting side by side, they frequently get the same
results when they start up
Am I missing somthing?
Any help would be appreciated
Have you tried a
statement just before the RND?
That should do it.

I have a workbook (Excel 2003) and I am having trouble with a particular
sorting issue. On page 2, column GL contains specific data that feeds into
formulas used in Page 1. When I sort my data on page 2 it changes the
formula totals on page 1.
What I want to do is have the ability to 'lock' the data on page 2 so that
after I sort it doesn't change the totals in my formulas using the Page 2
For example on Page 1, one of my cells reads the following formula:
='Rep Stack Ranking'!GL$12+'Rep Stack Ranking'!GL$13+'Rep Stack

I'm trying to creat an Excel macro that edits cell data, remembering the
edits, not just the resulting value or formula. If, for example, I want to
delete all but the last three characters of a cell value, and I record a
macro, editing the cell produces a line like: ActiveCell.FormulaR1C1 = "745".
But I don't want the specific value. I want the process.
I'm essentially asking for RIGHT(R1C1,3), but I can't use that formula in
the macro because it would be a circular reference. What am I missing?
If you use the Value property you can just replace the old v...Exchange server randomly asking random users to Authenticate randomly...

Is it possible to merge two columns of data into a single column, such that
the resultant column will contain cells of text consisting of the
*concatenation* of the two columns?
In other words, let's say I have two columns -- A & B -- each with many rows
of cells. In column A, I have a list of First Names; in column B, I have a
list of Last Names. What I'd like to do is to merge them into a single
column of First and Last Names.
I know I can create a function (in a third column, for instance) for every
single row, where column C would use a CONCATENATE function to merge t...Formatting Imported Data

Can someone help me with the following problem in Excel 2000:
in a table I have attached serveral cells with unique cell names, the
values in these cells are used in other sheets.
the problem is that when I sort the table, the cell names stay in the
original rowposition; they are not sorted! while their values are. So
Cell names get different values, and other calculations on my other
sheets get messed up!
How can I make the cell names relative instead of absolute?

I am using a table with multiple columns that are used as a database.
Each column is one data entry. I am having some hyperlinks that point
from one data entry (i.e. column) to another inside the spreadsheet.
Unfortunately, when I perform a sort of the columns, these hyperlinks
remain pointing to the previous location inside the sheet, i.e. to the
wrong column after the sort.
How do I solve this, i.e. how I make Excel understand that these
hyperlinks need to be updated while sorting the table?

You can record a macro when you do this:
Select the range

and ctrl-enter to fill all those empty (really empty) cells with 0's.
Or you could record a macro when you:
