Error using odearguments Vector Length issue

I am not sure I understand the issue here. Any help would be appreciated

%% Initial Variables
s1=0.27; s2=1.04; s3=0.716; s4=0; s5=0; Vref=1.04; Pref=0.716;
%% Define Diferential Equations
function dsdt= pv_system(t,s)
    %parameters
    Ki=20; Kp=4; Kip=10; Kiq=10; Tr=0.02; TGpv=0.01; Rq=0; Rp=0.05;
    Vref=1.04; Qactual=0.27; Vt=1.04;Pref=0.716;DeltaOmega=0;Pactual=0.716;
    Qcmd =0.27;
    %State Variables
    s1=s(1); s2=s(2); s3=(s); s4=s(4); s5=s(4);
    %diferential Equations
    ds1dt=Ki*(Vref-s2-Rq*Qactual);
    ds2dt = (1 / Tr) * (Vt - s2);
    ds3dt = (1 / TGpv) * (Pref - (DeltaOmega / Rp) - s3);
    ds4dt = Kip * (s3 - Pactual);
    ds5dt = Kiq * (Qcmd - Qactual);
    dsdt = [ds1dt; ds2dt; ds3dt; ds4dt; ds5dt];
end
%% inital Vector
s0 = [s1;s2;s3;s4;s5];
%% Time span for simulation
tspan = [0 10]; % 0 to 10 seconds
%% Solve using ode45
[t, s] = ode45(@pv_system, tspan, s0);

Error using odearguments (line 98)
PV_SYSTEM returns a vector of length 13, but the length of initial conditions vector is 5. The vector returned by PV_SYSTEM and the initial conditions vector must have the same number of elements.

Error in ode45 (line 104)
odearguments(odeIsFuncHandle,odeTreatAsMFile, solver_name, ode, tspan, y0, options, varargin);

[Torsten]

s3 = s(3)
s5 = s(5)

instead of

s3=(s)
s5=s(4)

Thank you so much, cant believe my dyslexia sstruck at the worst time.
