Deleting Duplicates while ignoring blank cells in VBA - excel

Question

I have some code in VBA that is attempting to delete duplicate transaction IDs. However, i'd like to ammend the code to only delete duplicates that have a transaction ID - so, if there is no transaction ID, i'd like that row to be left alone. Here is my code below:
With MySheet
newLastRow = .Range("A" & .Rows.Count).End(xlUp).Row
newLastCol = .Cells(5 & .Columns.Count).End(xlToLeft).Column
Set Newrange = .Range(.Cells(5, 1), .Cells(newLastRow, newLastCol))
Newrange.RemoveDuplicates Columns:=32, Header:= _
xlYes
End With
I was also wondering - in the remove.duplicates command - is there a way where I can have the column I want looked at to be named rather than have it be 32 in case I add or remove columns at a later date?
Here is an image of the data: I'd like the ExchTransID column that have those 3 blank spaces to be left alone.

Modify and try the below:
Option Explicit
Sub test()
Dim Lastrow As Long, Times As Long, i As Long
Dim rng As Range
Dim str As String
'Indicate the sheet your want to work with
With ThisWorkbook.Worksheets("Sheet1")
'Find the last row with IDs
Lastrow = .Cells(.Rows.Count, "A").End(xlUp).Row
'Set the range with all IDS
Set rng = .Range("A1:A" & Lastrow)
'Loop column from buttom to top
For i = Lastrow To 1 Step -1
str = .Range("A" & i).Value
If str <> "" Then
Times = Application.WorksheetFunction.CountIf(rng, str)
If Times > 1 Then
.Rows(i).EntireRow.Delete
End If
End If
Next i
End With
End Sub
