## Count Occurences of a Digit

These are serial numbers to containers that we own. My problem is that I need to order individual numbers to label these containers, and was wondering if there was a way to count the occurences of a single number so I know how many to order for each number.

There were perhaps 6 columns (in the test file), each having from 3 to fifteen five-digit numbers.

At the end of the test file, I found a new “wrinkle” that I chose to ignore. It called for totals by columns.

```Option Explicit

Sub CountOccursDigits()
Dim Ones, Twos, Threes, Fours, Fives, Sixes, Sevens, Eigths, Nines, Zeros
Dim daRow As Long, DaColm As Long, Jen As Long, Ez
Dim Z As Long, daTot
DaColm = Application.CountA(ActiveSheet.Range("1:1"))    'How many columns
For Jen = 1 To DaColm   	'Step thru columns
Cells(2, Jen).Select    'Got to row 2 in the current column
Selection.End(xlDown).Select    'Find the last row
daRow = ActiveCell.Row          'The row number
For Ez = 2 To daRow         'Step thru each cell in col
For Z = 1 To Len(Cells(Ez, Jen))    'Step thru each digit in cell
Select Case Mid(Cells(Ez, Jen), Z, 1)   'Eval the current digit
Case 1
Ones = Ones + 1
Case 2
Twos = Twos + 1
Case 3
Threes = Threes + 1
Case 4
Fours = Fours + 1
Case 5
Fives = Fives + 1
Case 6
Sixes = Sixes + 1
Case 7
Sevens = Sevens + 1
Case 8
Eigths = Eigths + 1
Case 9
Nines = Nines + 1
Case 0
Zeros = Zeros + 1
End Select
Next Z  'Next digit in cell
Next Ez     'Next row in column
Next Jen        'Next column
daTot = Ones + Twos + Threes + Fours + Fives + Sixes + Sevens + Eigths + Nines + Zeros
MsgBox "Ones: " & Ones & vbCrLf & "Twos: " & Twos & vbCrLf & "Threes: " & Threes _
& vbCrLf & "Four: " & Fours & vbCrLf & "Five: " & Fives & vbCrLf & "Six: " & Sixes _
& vbCrLf & "Seven: " & Sevens & vbCrLf & "Eight: " & Eigths & vbCrLf _
& "Nine: " & Nines & vbCrLf & "Zero: " & Zeros & vbCrLf & "--------" _
& vbCrLf & "TOTAL " & daTot, vbOKOnly, "Totals"     'Show box of totals
End Sub
```

What I came up with is 3 nested For…Next loops.
 The first counts the number of columns and begins stepping through them. The second determines how many rows are in the current column and begins stepping through the rows. And the last steps through each digit in the current cell and adds to either the Ones, Twos, Threes, etc.. I was surprised that I could do it in so few lines of code. And this is the MsgBox that displays at the conclusion.
