I'm trying to look at a works sheet and list all the unique items
found on that sheet in another sheet. The source sheet has around 50
columns of varying length. The following codes was slightly modified
from http://www.ozgrid.com/forum/showthread.php?t=39790 which comes
close to doing what I need. I need the area analyzed to be dynamic so
I added counting the used columns and rows (nCol and nRow) and tried
to work them into the code. the column count was pretty easy to work
in but the row count which seems to correspond to the upper bound of
"y" is not responding well to my attempts. Part of the problem is my
ignorance of the dictionary script thing that is implemented in the
code.

Any help will be appreciated.

Sub test()
Dim ws1 As Worksheet, ws2 As Worksheet
Dim dic As Object, w, y
Dim a, i As Long
Dim nCol As Integer
Dim nRows As Integer

Set dic = CreateObject("Scripting.Dictionary")
Set ws1 = Sheets("List") ' alter if needed


With ws1.Range("a1").CurrentRegion
a = .Value
End With

nCol = ws1.UsedRange.Columns.Count
nRows = ws1.UsedRange.Rows.Count


For i = LBound(a, 1) To UBound(a, 1)
If Not IsEmpty(a(i, 1)) Then
If Not dic.exists(a(i, 1)) Then
ReDim w(1 To nCol)
For ii = 1 To nCol
w(ii) = a(i, ii)
Next
dic.Add a(i, 1), w
Else
w = dic(a(i, 1)): w(nCol) = Val(w(nCol)) + Val(a(i,
nCol))
dic(a(i, 1)) = w
End If
End If
Next
y = dic.items: Set dic = Nothing
On Error Resume Next
Set ws2 = Sheets("Summary")
If ws2 Is Nothing Then
Set ws2 = Sheets.Add
ws2.Name = ("Summary")
End If
On Error GoTo 0
With ws2.Range("a1")
.CurrentRegion.ClearContents
With .Range("a1")
For i = LBound(y) To UBound(y)
.Offset(i).Resize(, UBound(y(i))) = y(i)
Next
End With
End With
Set ws1 = Nothing: Set ws2 = Nothing
Erase a, y, w
End Sub
