Determine Range to Select

Hi All,

I have the code below which currently selects a fixed range and hides columns where the value of the cell in row 1 is not blank but is zero.

Range("L1:YF1").Select
    Selection.EntireColumn.Hidden = False
    
    For Each Cell In Selection
        Count = Count + 1
    Next Cell
        
    Range("L1").Select
    For Ch = 1 To Count
        If ActiveCell.Value <> "" And ActiveCell.Value = 0 Then
        Selection.EntireColumn.Hidden = True
        Else
        End If
        ActiveCell.Offset(0, 1).Range("$A$1").Select
    Next Ch
Range("$K$2").Select

Question is, line 1 selects a fixed Range but I would like to change this to the equivalent of "Shift + Ctrl + End" ie from current cell to the last cell in the row. End Right won't work because there are gaps.

I could go to XFD1 and then do an End Left to determine the last column but how do I then convert that into the range to be selected.

For the second section of the code where I am using ActiveCell.Offset to move across one column at a time. I assume this is the "right" way to do it because I assume that if I did it with "For Each Cell in Selection.... Next Cell" I would end up hiding the whole selection each time. Happy to be corrected on that point.

As always, much appreciated.
Thanks
