I’m new to VBA as was trying to write a macro that finds duplicates in different columns from a worksheet. I found the answer here helpful. However this solved it only for one column. So to add a few more columns I altered the code as follows
Sub test()
Dim iWarnColor As Integer
Dim rng As Range
Dim rngCell As Variant
Dim iWarnColor1 As Integer
Dim rnga As Range
Dim rngCell1 As Variant
Set rng = Range("A1:A17") ' area to check '
iWarnColor = xlThemeColorAccent2
For Each rngCell In rng.Cells
vVal = rngCell.Text
If (WorksheetFunction.CountIf(rng, vVal) = 1) Then
rngCell.Interior.Pattern = xlNone
Else
rngCell.Interior.ColorIndex = iWarnColor
End If
Next rngCell
Set rnga = Range("B1:B17") ' area to check '
iWarnColor1 = xlThemeColorAccent3
For Each rngCell1 In rnga.Cells
vVal = rngCell1.Text
If (WorksheetFunction.CountIf(rnga, vVal) = 1) Then
rngCell1.Interior.Pattern = xlNone
Else
rngCell1.Interior.ColorIndex = iWarnColor1
End If
Next rngCell1
End Sub
On running this code I get
“Run time error 91: object variable or with block variable not set “
It says the error is at
For Each rngCell1 In rnga.Cells
What am I doing wrong here??
I can run your code locally in Excel 2010 without any errors, so not sure exactly what the problem is.
Try to change the type of rngCell1 from Variant to Range and see if it makes any difference.
As a side note, vVal has not been Dimed. It will only complain if you add Option Explicit at the top of your module, so it shouldn’t matter here.
