Hello all,

I am trying to use arrays for the first time and I am flummoxed! Although the array seems to be populating when I write the values to it, any attempt to read those values fail as nothing is returned. Now I KNOW that this is my stupidity and I have checked and rechecked the code that I cobbled together but I simply cannot see where I am going wrong. Any help would be hugely appreciated.

I would like to write the array to a range in Sheet1 but no values are returned and when I test with debug.print it seems that the array contains only 3 or 4 values instead of the dozens that were written to it. Please forgive my messy code!

Code:
'====DECLARE VARIABLES:'Declare Counter variables
'Dim x As Integer
Dim SheetCounter As Integer     'Used to count sheets
Dim MasterCount As Long         'Used to store number of unique keys

Dim TxnCounter As Integer       'Used to count transactions


'Declare Database variables
Dim UniqueKey As String         'Stores unique customer/household id
Dim MonthAdded As String        'Stores the month in which a household becomes a customer


'Declare Range variables

Thank for the reply, Fluff.

I tried to replicate the matrix in your example so Months are in A19:A30 and in C18:N18 in date format. I've checked that the code I added references the same cell offset as it does in your code but I've also tried moving the horizontal month row to row 17 as per your suggestion and get the same result.

May I be so forward to ask if I could send you a link to the worksheet to take a look if that would make it easier to see where I went wrong?

Excel Facts

Return population for a City
If you have a list of cities in A2:A100, use Data, Geography. Then =A2.Population and copy down.
I'm shortly off for the weekend, but if you post a link to the thread I will have a look at it when I get back.

Thanks for the file.
I don't get any errors, although you need to change the 3 occurrences of A17 to A16

Weird, I've changed the references but I still get the runtime 13 on that line. Any idea why that would be, that you don't but I do on the exact same workbook?

Aaaaarghhh! The csv data uses both a comma and period as a decimal separator!! That caused the error because it identified some amounts as number, others as text!

I'm 99% there now, I just need to figure out why the matrix for the amount is not populated like the customer count matrix. Still plugging away at this.

Update: Runtime error solved. It was due to dirty data in the CSV file that used both commas and periods as the decimal separator. Took me hours to figure that out!

Anyway, code runs without errors, there seems to be some calculation errors which I'm trying to debug but thank you again for all your help! You've been instrumental in getting me to this point. I appreciate your generous advice and your time, Fluff.

Glad you sorted out the error problem.
You nee to change the MRRArray to
Code:
               If Not Dic.Exists(UniqueKey) Then
                  Dic.Add UniqueKey, i
                  CustArray(i, 2) = CustArray(i, 2) + 1
                  [COLOR=#ff0000]MRRArray(i, 2) = MRRArray(i, 2) + RefCell.Offset(, 2).Value[/COLOR]
               ElseIf Not Dic2.Exists(UniqueKey) Then
                  Dic2.Add UniqueKey, Nothing
                  x = Dic.Item(UniqueKey)
                  CustArray(x, i) = CustArray(x, i) + 1
                [COLOR=#ff0000]  MRRArray(x, i) = MRRArray(x, i) + RefCell.Offset(, 2).Value[/COLOR]
               End If

You're welcome
Excellent weekend thanks (at least the bits I can remember)
