MATLAB: Problem with nested function

fminconfunctionminimizationnestednested functionwhile loop

I have a constrained minimization problem with objective function (in simplified form)
z=T*b1+p1*log(p1/(p1+p2+p3))+b2+p2*log(p2/(p1+p2+p3))+b3+p3*log(p3/(p1+p2+p3))
where 
%T is dependent variable which will be iterated using formula
T=25-p1-p2-p3
b1=a1*2,%(a1 is a constant input)
b2=a2*3,%(a2 is a constant input)
b3=a3*4,%(a3 is a constant input)
and constraints
2*p1+3*p2=A1,%(A1 is a constant input)
3*p2+5*p3=A2,%(A2 is a constant input)
p1>=0,
p2>=0,
p3>=0,
so, I wrote on my script   
function minimization
a1=input('a1=');
a2=input('a2=');
a3=input('a3=');
A1=input('A1=');
A2=input('A2=');
T=30%assumed T
while abs(T2-T)>0.1
T=0.5*(T2+T)
A=[];B=[];Aeq=[2,3,0;0,3,5];Beq=[A1;A2];wmin=[0.01;0.0;1;0.01];wmax=[];
optimal_p1p2p3=fmincon(@fozw,[0.1;0.1;0.1],A,B,Aeq,Beq,wmin,wmax);
function z=fozw(w);
p1=w(1);p2=w(2);p3=w(3);
z=b1+p1*log(p1/(p1+p2+p3))+b2+p2*log(p2/(p1+p2+p3))+b3+p3*log(p3/(p1+p2+p3));
end
T2=25-p1-p2-p3
end
end
Then, when I run the script. It appeared on command window
    function is misplaced or it is nested improperly
What is the possible error on my script?.

You cannot define functions or nested functions inside scripts. This is only allowed inside functions. Therefore insert the line "function YouFuncName" on top of the code, add needed inputs and outputs as usual.
