AgentSpeak: Problems at sending plan (Jason) - artificial-intelligence

Question

I'm trying to send a plan from Agent1 to Agent2 via:
#c2[atomic]
+giveRule[source(A)]: planGiven(B) <-
-+planGiven(B+1);
.send(A, tellHow, "#s1 +sum(num1(X, Y), num2(A, B))[source(S)] :logic(L) & attentiveness(T)<- if ((L + T) > 2){ -+res(num1(X, Y), num2(A, B), res(X*10 + A*10 + Y + B)); .send(S, tell, result(X*10 + A*10 + Y + B)); } else { -+res(num1(X, Y), num2(A, B), res(X + A + Y + B)); .send(S, tell, result(X + A + Y + B)); }.");
-+stopGivingPlan.
Then, i'm trying to make this plan work by sending a message from Agent1 to Agent2:
#c3[atomic]
+giveProbs[source(A)]: probsGiven(B) & stud(A,X)<-
-+probsGiven(B+1);
.send(A, tell, sum(num1(3,3), num2(4,9))).
It doesn't work.
Why?
And important addition:
If I don't send plan, and just copy it in Agent2, it works fine. so Syntax is ok.
Also, i'm using jason plugin in eclipse, if that's worth to be mentioned.

It is not quite clear what is being performed, it is better if you can show the whole code. I simplified the case just to try to show a general idea, as bellow:
Agent1 code:
!start.
+!start: true <-
.send(agent2, tellHow, "#s1 +!sum(num1(X, Y), num2(A, B))[source(S)] :true <- -+res(num1(X, Y), num2(A, B), res(X + A + Y + B)); ?res(Z1,Z2,Z3); .print(Z1,\"+\",Z2,\"=\",Z3).");
.send(agent2, achieve, sum(num1(1,2), num2(3,4))).
Agent2 code:
/* No previous code - agent1 will send a plan*/
The response should be:
[agent2] num1(1,2)+num2(3,4)=res(10)
In this case, agent2 has nothing to do until agent1 sends a plan. Agent1 is also sending a triggering plan to achieve a sum.
