Hi everyone i've tried to solve two coupled nonlinear ode but maple gives me these two errors can you help me with this?

ode1 := diff(f(x), x, x, x)+3*f(x)*(diff(f(x), x, x))-2*(diff(f(x), x))^2+g(x) = 0;
 ode2 := diff(g(x), x, x)+(3*10)*f(x)*(diff(g(x), x)) = 0;
 bcs1 := (D(f))(0) = 0, f(0) = 0, (D(f))(6) = 0;
 bcs2 := g(0) = 1, g(6) = 0;
 sys := {bcs1, bcs2, ode1, ode2};
 dsn := dsolve(sys, numeric);
 print(plots:-odeplot(dsn, [x, g(x)...

Hello

i have an ode equation which has a variable coefficient n. i solve my ode and the code gave me  single plot for specific n.  i want to draw these plots in one plot the code wich draw plot is :
