Problem with God object!

Hi guys,

i have a problem in my script, i have this instruction in one of my procedure:

…
set connectivity_prob_sample [expr 1.0*[$god_ set num_connect]/$max_num_connections_]
…

and this is the error in the shell:

ns: connectivity_process_sample: can’t read “num_connect”: no such variable
while executing
“subst $[subst $var]”
(procedure “_o12” line 5)
(SplitObject set line 5)
invoked from within
“$god_ set num_connect”
(procedure “connectivity_process_sample” line 5)
invoked from within
“connectivity_process_sample”

I have create the god object before, but how can i use num_connect from god object???
