Set Ranges Throwing Unknown Error

Hi all,

The following code is a part of a function that I am working on.

Private Function FindIntersect(ByVal DtRng As Range, FndSel As Range, Region As String, IndBool As Boolean)
    Dim cl As Range, Dts As Range
    '''''''''''''''''''''''''''''''''''''''''''''''''''''''''
    '''ValArrayF() is for values that are not user indexed'''
    '''ValArrayT() is for values that are user indexed    '''
    Dim ValArrayF() As Double, ValArrayT() As Double
    Dim DisplayDtRng As Range, DisplayFndSel As Range
    Dim AryCnt As Long, AryCntr As Long
    Dim DtCnt As Long, rCnt As Long, cCnt As Long
    Dim Ws1 As Worksheet, Ws2 As Worksheet, Ws3 As Worksheet
    Set Ws1 = Worksheets("Qrtr")
    Set Ws2 = Worksheets("Sheet2")
    Set Ws3 = Worksheets("Sheet3")
    AryCnt = DtRng.Cells.Count
    AryCntr = 0
    If IndBool = False Then
        ReDim ValArrayF(AryCnt)
    Else:
        ReDim ValArrayT(AryCnt + 1)
    End If
    Set Dts = Ws2.Range("B19").Resize(, AryCnt)
    Debug.Print Dts.Address        '''Debugs as $B$19:$G$19
    Debug.Print DtRng.Address    '''Debugs as $C$7:$C$12
    Dts.Cells.Value = DtRng.Cells.Value
    With Dts.Cells
         .Interior.ColorIndex = xlNone
         .BorderAround xlSolid, xlMedium
         .Font.Bold = True
         .Font.Size = 12
    End With
    '....More Code....'
End Function

This code worked up until I added

With Dts.Cells
         .Interior.ColorIndex = xlNone
         .BorderAround xlSolid, xlMedium
         .Font.Bold = True
         .Font.Size = 12
    End With

and now for some reason stops at

Dts.Cells.Value = DtRng.Cells.Value

I can't for the life of me see why! Also, the error prompt is a none descriptive message with a big X on the left side and the number 400 on the right. If anyone can see why I would appreciate your comments. Until then, I guess debugging each line of code for my whole project may be needed.

Thanks
