VBA to Filldown Every Other Column with Formula

The code below should enter a formula beginning in column O (15th column) followed by every other column until the 93rd column on the "Winshuttle" worksheet. Instead, the code is starting on column S or V. How do I get this to start in the 15th column?

Sub QtyFillDown()
    Dim QCol As Long, QLastrow As Long
    
    With Worksheets("Winshuttle")
        QLastrow = .Range("J" & Rows.Count).End(xlUp).Row
        For QCol = 15 To 93 Step 2
            .Range(.Cells(2, QCol), .Cells(QLastrow, QCol)).Formula = _
                "=IF(VLOOKUP($J2,Template," & QCol / 2 + 2 & ",FALSE)="""","""",VLOOKUP($J2,Template," & QCol / 2 + 2 & ",FALSE))"
        Next QCol
    End With
End Sub
