Hide Entire given rows if a specified cell is blank - excel

Question

I am a newbie in VBA coding.
I am trying to achieve that inside my function
sub Private Sub Worksheet_Change(ByVal Target As Range)
where it checks some specified cells value change to run a given macro. The additional macro that i want to add is that when ever cell a62 is Empty, it will hide rows a56:a61. and consecutively if a82 is empty, it will hide rows a78:a82.
i have the following code but it only hides the rows from the first empty cell until end of sheet.
Sub Test()
Dim i As Long
For i = 4 To 800
If Sheets("Results").Cells(i, 1).Value = "" Then
Rows(i & ":" & Rows.Count).EntireRow.Hidden = True
Rows("1:" & i - 1).EntireRow.Hidden = False
Exit Sub
End If
Next
End Sub

Please, check the next event code:
Option Explicit
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$A$62" Or Target.Address = "$A$82" Then
Select Case Target.Address
Case "$A$62"
If Target.Value = "" Then
Range("A56:A61").EntireRow.Hidden = True
Else
Range("A56:A61").EntireRow.Hidden = False
End If
Case "$A$82"
If Target.Value = "" Then
Range("A78:A81").EntireRow.Hidden = True
Else
Range("A78:A81").EntireRow.Hidden = False
End If
End Select
End If
End Sub
It will be triggered only if you MANUALLY change the value of one of the two required cells.
If their value is the result of a formula, Worksheet_Calculate event must be used, but in a different way. This event does not have any argument (no Target) and you must check the two cells in discussion and act according to their value, independent if they were changed or not when the Calculate event is triggered. If this is the case, I can post such an event code, too.
Edited:
For the version which does not involve the manual changing of the values, please copy this event code in the sheet code module:
Private Sub Worksheet_Calculate()
If Me.Range("A62").Value = "" Then
Me.Range("A56:A61").EntireRow.Hidden = True
Else
Me.Range("A56:A61").EntireRow.Hidden = False
End If
If Me.Range("A82").Value = "" Then
Me.Range("A78:A82").EntireRow.Hidden = True
Else
Me.Range("A78:A82").EntireRow.Hidden = False
End If
'Edited:
'The part for both analyzed ranges being empty:
If Me.Range("A62").Value = "" And _
Me.Range("A82").Value = "" Then
'Do here what you need...
End If
End Sub
