 What Daniel was saying was that in the second notebook you should expect NSolve to give a lot of warning messages because the foc1 == 0 equation has no Real solution for A==0.

 I think you didn't get my question... Bill Simpson got it; and i hope he will clarify also my new doubt :)

 C'mon, look at what you have. Your first equation cannot be zero when you set A to zero. {foc1, foc2} /. A -> 0 (* Out[12]= {-1, 0} *) This is not the sort of thing that should be sent to an entire forum for analysis.

 . In[6]:= m = Table[{{A, X, Y, p} /. NSolve[{foc1 == 0, foc2 == 0}, {X, Y}, Reals]}, {A, 0, 2, 1/10}] Out[6]= {{{0, X, Y, 0}}, {{{1/10, 0.0137388, 0.314177, 0.0437295}}}, {{{1/5, 0.0293842, 0.289732, 0.101418}}}, etc, etc, etc

 Enter the code you wrote as code rather than an image. That way it will be both readable and cut-and-pasteable by others.

 if you don't understand the question just ask!To sum up, by a simple system of equation i get different value of X and Y. For each of these solution i want to calculate p which is a function of X and Y itself!
