Using IF to restart macro when cell is a particular value

Hi.

Sorry for the bad thread title but I didnt know what else to write

Anyway, here is my problem.
I have a macro that runs through a bunch of external .xls files based on a list in my primary workbook.
What I want to do happen is that if I put an "x" in the adjacent cell of my list, the macro should change a cell value and then go to the next item in the list.

My code is becoming quite big so I wont post all of it but I think this will be enough.
The blablablabla lines shows where I have omitted some code

Do

'Defines the name of the file for running external macro
Dim sName As String
    sName = ActiveCell.Value

blablabla

If ActiveCell.Offset(0, -1).Value = "x" Then
Sheets("S01-01-0103").Select
    Range("B3").Select
    ActiveCell.Offset(0, Sheets("Macros").Range("G1") + 1).Select
    ActiveCell.Offset(-1, 0).Select
    ActiveCell.Value = sName

    Sheets("Macros").Range("G1") = Sheets("Macros").Range("G1") + 1
    
    Sheets("Macros").Select
    Range("F1") = Range("F1") + 1
    
    ActiveCell.Offset(1, 0).Select

   Else
     
End If


blablalblalbla


'Loops this macro until the list is empty
Loop Until IsEmpty(ActiveCell.Offset(0, 0))

All I want to know is what do I write after

ActiveCell.Offset(1, 0).Select

for the macro to restart, in other words, go back to "Do".
I have everything else working fine,
