Concatenating Using Case Statement with Multiple Conditions - excel

Question

I'm trying to concatenate Tier Code and Cap Code where Cap Level = 2. I was able to successfully do the concatenation earlier using a case statement, without the condition that Cap Level = 2. However, now that I'm trying to add that condition, I keep getting the error "Type Mistmatch". I've tried setting Range("E3:E24").Value = 2 and = "2". Both ways, I still get the error.
My data currently looks like this:
I've been playing around with this for at least an hour now and reading other questions about case statements with multiple conditions/criteria, but I haven't been able to get my code to work properly.
Sub Concat_ParentCode_Cap1_001()
With Worksheets("PD Code Structure")
Dim ParentCode As Range
Dim TierCode As String
Dim CapCode As String
CapCode = "FS_CAP_1_001"
TierCode = "FS_Tier_1"
Set ParentCode = Range("F3:F24")
Select Case True
Case CapCode = "FS_CAP_1_001" And Range("E3:E24").Value = "2"
ParentCode = TierCode & "." & CapCode
End Select
End With
End Sub
I would like my data to look like this:

Answer 1

There are a few things in the code provided that will cause it not too work, but the main thing is a loop to check each cell.
Give this a shot:
Option Explicit
Sub Concat_ParentCode_Cap1_001()
Dim tierCode As String
tierCode = "FS_TIER_1."
With Worksheets("PD Code Structure")
Dim capCode As Range
For Each capCode In .Range("F2:F24")
If Len(capCode.Offset(, -1)) Then
Dim capParent As String
capParent = capCode.Value
End If
If capCode.Offset(, -2).Value = 2 Then
capCode.Offset(, -1).Value = tierCode & capParent
End If
Next
End With
End Sub

Do you really need to use VBA for this ? This looks like something you can do with just an if statement on excel. =if(B2=2,CONCAT(A1,".",D1),""). This is of course assuming the columns are listed A-D above.
