Can anyone help with this macro ?

I need it to hide any rows which have a value of 0 in cols A to H

I DON'T want to use filters.

Every time I run it, nothing is hidden

Thanks in advance



Sub Hide_Print_Unhide()
Dim rw As Long
Application.ScreenUpdating = False

With Sheets("Sheet1")
For rw = 1 To 300
If Application.WorksheetFunction.CountA( _
.Cells(rw, 1).Range("A1:H1")) = 0 Then _
.Rows(rw).Hidden = True
Next rw
.PrintOut
.Range("A1:A300").EntireRow.Hidden = False
End With

Application.ScreenUpdating = True
End Sub
