Hiding Reference Errors using Font colour in VBA - vba

Question

Hi there i have this code which changes cells with reference errors to white fonts. However i could only do so for a single sheet. range. How do i change the for each loop to loop for all the worksheets in the workbook? I used this code below but it does not seem to work!
Sub Delete_ref_basedontextcondition()
Dim R As Range
'Set rng = Nothing
On Error Resume Next
Set R = Application.InputBox("Select cells To be deleted", Type:=8)
Dim rng As Range
If TypeName(R) <> "Range" Then
Exit Sub
Else
R.Delete
End If
For k = 1 To ThisWorkbook.Worksheets.Count 'runs through all worksheets
Set wks = ThisWorkbook.Worksheets(k)
For Each cell In wks
If cell.Text = "#REF!" Then
cell.Font.Color = RGB(255, 255, 255)
End If
Next
Next
End Sub

While I disagree with your method of hiding #REF! errors rather than dealing with them so that they are not #REF! errors (or deleting the formulas that are creating them, here is some standard 'loop-through-the-worksheets' code that you should be able to adapt for your purposes.
Sub bad_ref()
Dim w As Long, ref As Range
On Error Resume Next
For w = 1 To Worksheets.Count
With Worksheets(w)
For Each ref In .Cells.SpecialCells(xlCellTypeFormulas, xlErrors)
If ref.Text = "#REF!" Then
ref.Font.ColorIndex = 2
'ref.clear '<~~this clears formatting, formulas. etc from the rogue cell.
End If
Next ref
End With
Next w
End Sub
It should run through quickly enough. Rather than examine every cell on each worksheet, I've narrowed down the cells to be critiqued with the Range.SpecialCells method, looking only through the formulas that produce errors. Something like a #N/A error will be left alone.
I've left an option to actually do something with the errors as a commented line.
