Help with ODE45 solver issue

Hello

Im working on a group project for a course, and when attempting to run my code i am given these errors in this sequence:

Error in ode45 (line 115)

odearguments(FcnHandlesUsed, solver_name, ode, tspan, y0, options, varargin);

Error in projectbees (line 18)

[t,states] = ode45(@beederivatives2, [t0 tend], states0, options);

It has happened sevral times not only with this project, but with other codes as well, and for the most part, my group and I's codes are the same (aside from some varying initial conditions) I was wondering if anyone could help me out. Files linked below if needed.
