Swapping columns Error 2

[jomili]

I previously posted about a problem I was having with Rick's column swap macro (http://www.excelfox.com/forum/f22/swapping-rearranging-multiple-columns-data-493/index2.html). Now I'm back again, with example included. My problem is my last column, "Subject". In the B4 picture, it's at the extreme right-end. In the "After" picture, it's still there, AND in column E, where it's supposed to go. But my "Contract Manager" column disappears.

The macro, as configured, is in the attachment.

Okay, I've achieved partial success by changing my column order to add the last column (AB, the one that disappears) twice:
Const NewOrder As String = "D,E,AD,AE,AF,AC,B,C,F,G,H,I,J,K,L,M,N,P,X,Y,Q,R,S, T,U,V,W,A,AA,O,Z,AB,AB"I'd like to know if this is a regular thing, or if there's a code change that could correct this. I don't understand Rick's code well enough to understand why it's having this problem.
