My problem is, that when using the VlookUp I do get the Error:
The VLookup-Property of the WorksheetFunction-Object could not be assigned
' LookUp missing Data
Dim lookupRange As Range
Set lookupRange = Sheets("Kundenlisten HLK 2018").Range("A1:Y10354")
' Fill in Companyname
Dim tmp As String
tmp = Values(0)
tmp = TrueTrim(tmp)
testing.Cells(8, counter) = Application.WorksheetFunction.VLookup(tmp, lookupWS.Range("A2:Y10354"), 2, False)
Values = None
counter = counter + 1
lookupWS is the Name of the Worksheet As you can see the table I am trying to lookup is filled with values from A to Y. The first column is the key I am trying to look up, but then the error from above occurs. The tmp variable is a String with a unique ID to look up the missing values, while the "2" is supposed to be the company name in the second column of the Range.
I looked up on the docs, but the types and everything are fine, I even checked while debugging.
testing.Cells(8, counter) can't be the source of the problem aswell, since I am using it before like this
testing.Cells(28, counter) = Left(mail.ReceivedTime, 10)
and it works
