Plotting in app designer doesn´t shows anything

Hello people i have this problem of plotting on app designer and i don´t know what the problem could be. When i run the program the graph doesn´t shows anything. I have this code

function Plot_BVButtonPushed(app, event)

m = app.masa.Value;

d = app.delta.Value;

v = 0:5:60;

lf = 1.11;

lr = 1.6;

l = lf + lr;

Kr = 55000;

Kf = 60000;

beta = ((1-((m*lf)/(2*l*lr*Kr))*v.^2)/(1-(m/(2*l^2))*((lf*Kf-lr*Kr)/(Kr*Kf))*v.^2))*(lr/l)*d;

plot(app.BV,v,beta, 'r');

If anyone could help i will apreciate it, please.

%if true
beta =  ((1-((m*lf)/(2*l*lr*Kr))*v.^2)./(1-(m/(2*l^2))*((lf*Kf-lr*Kr)./(Kr*Kf))*v.^2))*(lr/l)*d

Do element wise division for v.^2 as above

That fixed out the problem. Thank you very much.
