Tim Williams is absolutely correct about adding a new worksheet.
However your logic appears to be flawed. Your code only works if there isn't a worksheet named "Logix Friendly" and there is only 1 sheet in the workbook.
What you should be doing:
For Each ws In ThisWorkbook.Worksheets
bWS_Found = (InStr(1, ws.Name, "Logix Friendly", vbTextCompare) = 1)
' Exit checking if a worksheet already named "Logix Friendly"
If bWS_Found Then Exit For
Next
' Add worksheet if there isn't a "Logix Friendly" worksheet
If Not bWS_Found Then
With ThisWorkbook.Worksheets.Add
.Name = "Logix Friendly"
End With
End With
