User-defined function error: V is undefined

[qiyan31]

I made a user-defined function for Height.
function Ht=Height(t,V,Theta);
Ht=V*t*sin(Theta)-4.9*t.^2;
end

V is initial velocity, and i kept on getting input "V" is undefined.
Can someone help me please!

Works fine for me. What is the precise command that you're using to test the function?
