Countblank - Need code to update countblank numbers as data is updated

Hello,

I have a workbook that compares each spreadsheet against a list of required fields in another workbook and returns a row of countblanks for each required field. My boss has asked if I could have the countblank numbers change as we update the data in the blank fields. I have attached the spreadsheet for your reference. The current code is listed below. Any assistance would be greatly appreciated.Excel Compare Test Updated.xlsx

Sub CompareTest()
    Dim wbCompare As Workbook
    Dim wbField As Workbook
    
    'if code is running from a compare test file
    Set wbCompare = ThisWorkbook
    
    'prompt to open compare test file
    'cancel this first prompt if code is already running from compare test file
    Ref_WBook = Application.GetOpenFilename("Excel File (*.xls), *.xls", Title:="Select Compare File")
    If Ref_WBook <> "False" Then
        Workbooks.Open Ref_WBook
        Set wbCompare = ActiveWorkbook
    End If
    
    'prompt to open required field file
    Ref_WBook = Application.GetOpenFilename("Excel File (*.xls), *.xls", Title:="Select Field File")
    If Ref_WBook <> "False" Then
        Workbooks.Open Ref_WBook
        Set wbField = ActiveWorkbook
    End If
    
    
    'find last filled row in sheet 1
    With wbCompare.Sheets(1)
        rowsInB = .Range("B" & .Rows.Count).End(xlUp).Row
    End With
    
    'insert row at top for counting blanks
    For i = 1 To wbCompare.Sheets.Count
        wbCompare.Sheets(i).Range("A1").EntireRow.Insert
    Next
    
    'loop for all required fields
    fieldRow = wbField.Sheets(1).Range("A" & Rows.Count).End(xlUp).Row
    For fRow = 2 To fieldRow
        fieldValue = wbField.Sheets(1).Range("A" & fRow).Value
        
        'loop through sheets in compare test file
        For sheetIndex = 1 To wbCompare.Sheets.Count
            
            For searchRow = 2 To rowsInB + 1
                With wbCompare.Sheets(sheetIndex)
                    For searchCol = 1 To .Columns.Count
                        
                        'try finding the value and color the cell
                        If .Cells(searchRow, searchCol).Value = fieldValue Then
                            .Cells(searchRow, searchCol).Interior.Color = RGB(255, 255, 0)
                            .Cells(1, searchCol).Value = _
                                Application.WorksheetFunction.CountBlank(.Range(.Cells(2, searchCol), .Cells(rowsInB + 1, searchCol)))
                        End If
                        
                    Next
                End With
            Next
            
        Next
    Next
    
    wbCompare.Activate
End Sub
