I've been trying to figure out what I'm doing wrong, but cant seem to find it, its a 2 part code:

clear all
function dy = juan(t,y)
global k1 k2 k3 kmin3 k4 k5 k6 k7
dy=zeros(6,1);
dy(1)=k1-k2.*y(1).*y(5);
dy(2)=k2.*y(1).*y(5)+kmin3.*y(3)-k3.*y(2);
dy(3)=k3.*y(2)+k5.*y(4)-k4.*y(3).*y(5)-k3.*y(3);
dy(4)=k4.*y(3).*y(5)-k5.*y(4)-k6.*y(4);
dy(5)=k7.*y(6)-k2.*y(1).*y(5)-k4.*y(3).*y(5);
dy(6)=-k7.*y(6)+k2.*y(1).*y(5)+k4.*y(3).*y(5);
end

That first part defines my ecuations, and the next one asignes values to k's, but always get errors even when its the same code as my professor

global k1 k2 k3 kmin3 k4 k5 k6 k7
k1= 0.25; 
k2= 1; 
k3= 1;
kmin3= 1; 
k4= 1; 
k5= 1; 
k6= 1; 
k7= 2.5;
