How can I append output to a list then plot the list.


Below I have an excerpt from a program that solves a profit maximizing problem and reports the profits of firm 1 then firm 2.  I would like to add an additional element to this.  I would like to assume firm 1 has developed technology that decreases costs by a certain amount every time period (iteration).  As a result, although both firms made equal profits in the first time period, firm 1 will enjoy increased profits over time while firm 2's profits will remain constant.  I have generated the appropriate output but I can't get my code to work so that I can plot both profit functions (firm 1 and firm 2) out together on the same graph.  can anyone make any sense out of the code provided below?

CODE

=====

(list1=Table[{x,x1},{x,1,10,1}];

list2=Table[{x,x2},{x,1,10,1}];);

For[i=1,i<5,i++,Print[CournotProfit1];

Print[CournotProfit2];

Cost1=Cost1-.1Cost1;

Print["new cost firm1"];

Print[Cost1];

CournotProfit1=Simplify[q1cournot*(Pcournot-Cost1)];

CournotProfit2=Simplify[q2cournot*(Pcournot-Cost2)];

x1=CournotProfit1;

x2=CournotProfit2;

Append[list1,x1];

Append[list2,x2]]

MultipleListPlot[list1,list2]

OUTPUT (profits for firm 1 and firm 2 over time (iterations))
