excel VBA - Loop of an array - excel

Question

I made this simple code, or at least tried. But I have one small problem.
When I type For I = 14 To 25 I don't really know what I'm doing. I have a sheet called "Master" and in the range K6:V6 I have every name of every sheet I want to go through. I would like to write something like this: For I = sheets("Master").range("K6:V6") But this does not work, anyone that can help to me to assign the "names" in this array to I?
The rest of the code works as it should, it could be optimized by not having "select" but I don't seem to be able to do it so I took the easy way out. Thank you for your help!
Dim I As Integer
For I = 14 To 25
If Sheets(I).Visible = False Then
'If sheet = Not visble
'-----------------------------------------------------------------------------------------------------
Sheets(I).Visible = True
AA = Sheets("Master").Range("K6").Value
Sheets(AA).Select
ActiveSheet.Unprotect
ActiveSheet.Range("C3:C120").Copy
Range("G3").Select
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False
ActiveSheet.Range("C6:C120").ClearContents
ActiveSheet.Range("L6:M117").ClearContents
ActiveSheet.Protect
Range("A1").Select
Sheets(I).Visible = False
'-----------------------------------------------------------------------------------------------------
Else:
'If sheet = visble
'-----------------------------------------------------------------------------------------------------
AA = Sheets("Master").Range("K6").Value
Sheets(AA).Select
ActiveSheet.Unprotect
ActiveSheet.Range("C3:C120").Copy
Range("G3").Select
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False
ActiveSheet.Range("C6:C120").ClearContents
ActiveSheet.Range("L6:M117").ClearContents
ActiveSheet.Protect
Range("A1").Select
'-----------------------------------------------------------------------------------------------------
End If
Next I

Each Worksheet in a file is held in the Worksheets collection. You can look at each worksheet in the collection in turn and act on it.
Sub Test()
Dim wrkSht As Worksheet
Dim shtMaster As Worksheet
Dim InList As Range
Dim VisibleSetting As Long
Set shtMaster = ThisWorkbook.Worksheets("Master") 'Reference to Master worksheet
'This will look at each worksheet in the worksheets collection and reference it with 'wrkSht'
For Each wrkSht In ThisWorkbook.Worksheets
'Look for the worksheet name in the K6:V6 range.
Set InList = shtMaster.Range("K6:V6").Find(wrkSht.Name, LookIn:=xlValues, LookAt:=xlWhole)
'If the name is found InList will not be nothing.
If Not InList Is Nothing Then
With wrkSht
VisibleSetting = .Visible 'Remember the visible setting.
.Visible = xlSheetVisible
.Unprotect
.Range("C3:C120").Copy
.Range("G3").PasteSpecial xlPasteValues
Union(.Range("C3:C120"), .Range("L6:M17")).ClearContents
.Visible = VisibleSetting 'Put the visible setting back.
.Protect
End With
End If
Next wrkSht
End Sub
