FVWM: $[page.nx] etc. not functioning

[msibley]

Howdy, 

I have a 3x3 DeskTop 

# .fvwmconfig 
Key F8 A A Exec xmessage $[desk.n] $[page.nx] $[page.ny] $[w.id]

I hit f8 while focused in a window in the bottom right page

# xmessage output
0 0 0 0x1400002

I should get:
0 2 2 -x1400002 

Am I correct? 

I am running 2.6.4 

Thanks!
