salve
prova con questa:
Sub cerca()
Application.ScreenUpdating = False
Dim Myvalue As Long
Myvalue = InputBox("DIGITA IL VALORE DA CERCARE", "CERCA VALORE")
For n = 1 To Cells(1, 1).End(xlDown).Row
Set area = Range(Cells(n, 1), Cells(n, 35))
For Each cl In area
If cl = Myvalue Then
With cl
.Interior.ColorIndex = 36
.Borders.LineStyle = xlContinuous
.Borders.Weight = xlMedium
End With
End If
Next cl
Set area = Nothing
Next n
Application.ScreenUpdating = True
End Sub
