Quiero usar el siguiente código:

Private Sub Worksheet_Change(ByVal target As Range)

On Error Resume Next
If Intersect(target, Range("??")) Is Nothing Then GoTo Einde
If IsEmpty(target) Then GoTo Einde

If Hour(target.Value) <> 0 Or Minute(target.Value) <> 0 Then GoTo Einde
Application.EnableEvents = False
If Int(target.Value / 100) < 0.1 Then
target = "00:" & target.Value
Else
target = Int(target.Value / 100) & ":" & Right(target.Value, 2)
End If
Application.EnableEvents = True

ActiveSheet.Calculate
End Sub

Los dos signos de interrogación en la tercera línea de código deben ser el siguiente rango:

Dim aRng, bRng, cRng, dRng, uRng As Range
Set aRng = Range("B5,B7,B9,B11,B13,B15,B17,B19,B21,B26,B28,B30,B32,B34,B36,B38,B40,B42,B47,B49,B51,B53,B55,B57,B59,B61,B63,B68,B70,B72,B74,B76,B78,B80,B82,B84,B89,B91,B93,B95,B97,B99,B101,B103,B105,B110,B112,B114,B116,B118,B120,B122,B124,B126,B131,B133,B135,B137,B139,B141,B143,B145,B147")
Set bRng = Range("F5,F7,F9,F11,F13,F15,F17,F19,F21,F26,F28,F30,F32,F34,F36,F38,F40,F42,F47,F49,F51,F53,F55,F57,F59,F61,F63,F68,F70,F72,F74,F76,F78,F80,F82,F84,F89,F91,F93,F95,F97,F99,F101,F103,F105,F110,F112,F114,F116,F118,F120,F122,F124,F126,F131,F133,F135,F137,F139,F141,F143,F145,F147")
Set cRng = Range("J5,J7,J9,J11,J13,J15,J17,J19,J21,J26,J28,J30,J32,J34,J36,J38,J40,J42,J47,J49,J51,J53,J55,J57,J59,J61,J63,J68,J70,J72,J74,J76,J78,J80,J82,J84,J89,J91,J93,J95,J97,J99,J101,J103,J105,J110,J112,J114,J116,J118,J120,J122,J124,J126,J131,J133,J135,J137,J139,J141,J143,J145,J147")
Set dRng = Range("N5,N7,N9,N11,N13,N15,N17,N19,N21,N26,N28,N30,N32,N34,N36,N38,N40,N42,N47,N49,N51,N53,N55,N57,N59,N61,N63,N68,N70,N72,N74,N76,N78,N80,N82,N84,N89,N91,N93,N95,N97,N99,N101,N103,N105,N110,N112,N114,N116,N118,N120,N122,N124,N126,N131,N133,N135,N137,N139,N141,N143,N145,N147")
Set uRng = Union(aRng, bRng, cRng, dRng)'

Pero no puedo hacer que funcione.

Alguien tiene alguna idea de dónde está el problema?

Gracias por tu aporte.
