Please help!

The codes are below, Gourbi does not give solution, where is wrong with the codes?

 

max (q1+...q6), st. g*q<P, b1*q<W, 0.2P+0.4W<300000, P>0.W>0

q=[q1, q2, ... g6] is integer 

P,W, are real. 

 

 

clear; clc;
names = { 'q1' ; 'q2' ; 'q3' ; 'q4' ; 'q5' ; 'q6' ; 'P';'W'};
g=[4.9 9.5 33.1 120.2 457.1 1778];
b1= [ 100 50 25 12.5 6.25 1.563]*10;

pw1 = [g -1 0];
bw1 = [b1 0 -1];

user_max = 0;
try
clear model ;
model.A = sparse([pw1;bw1; [zeros(1,6) 0.4 0.2]]);

model.obj = ones(1,6); %% objective is on all users
model.rhs = [0 0 300000 ];
model.sense = '<<<' ;
model.vtype(1:6) = 'I' ;
%model.vtype(7:8) = 'C';

model.modelsense = 'max' ;
clear params ;
params.outputflag = 0;
params.resultfile = 'mip10.lp' ;
result = gurobi(model, params);
disp(result)
