invalid receiver type 'void'

[Krishnan Viswanathan]

I downloaded the source codes for the articles in "Econ. Sim. in Swarm"
from Paul Johnson's site. On running the code for chapter 7 - Numerical
Modeling, Noise Traders and the Swarm Sim. Sys. I got the following
error on make.
******************************************************************
MktModelSwarm.m:330: warning: invalid receiver type `void '
MktModelSwarm.m:330: void value not ignored as it ought to be
MktModelSwarm.m:330: invalid use of void expression

The relevant code for this is:
traderElement = [wealthGraph createElement];
[[[traderElement setLabel: "all traders"] setColor: "black"] setWidth:
3];
*************************************************************************

Any help or pointers on fixing this is much appreciated.

Thanks
Krishnan
