Output Argument not assigned during call

Good afternoon everyone,
I've been tasked to create a fairly simple code (which I've done for the most part). The code always gives the correct answers, however the grader that I must submit to presents this error:
Output argument "MaxPower" (and maybe others) not assigned during call to "MaxPowerSolver".
function MaxPower = MaxPowerSolver(ElectricalData)
Power = ElectricalData(:,2).*ElectricalData(:,3);
MaxPower = max(Power);
end
Where Electrical data is given by [t,v,i] ([time, voltage, current]).
I can't seem to work this one out after googling and researching other people's similar problems.
Please help, thank you for your time.

Somehow it is grading some other version of your code. Make sure you do not have any other function of the same name that it could be finding.

Yeah, you're certainly assigning the value to MaxPower. A couple of possibilities strike me:
Are you actually calling this particular function? Is it perhaps shadowed by something else on the path that has a different output assignment? Type:
which MaxPowerSolver
Or Is it potentially in the calling function? If it also calls a variable MaxPower but forgets to assign it, perhaps you're seeing an error meant for a different file? (e.g. its handling assigns to "maxPower" or "MaxPowe" by mistake.) Something maybe like:
function MaxPower = evalInputFunction(func, e_data)
%
MaxPowe = func(e_data) % This is the actual failure point
end
load the_data
passfail = zeros(1,numel(test_functions))
for ix = 1:numel(test_functions)
fx = test_functions(ix) % Your MaxPowerSolver is test_function(17), for instance
Pmx = evalInputFunction(fx, the_data)
if Pmax == Correct_P
passfail(ix) = 1
end

Hi Jesse,
The error you had mentioned will occured only in the case when the output Variable "MaxPower" is not assigned in the function but as i can see it should work fine.
You may try following function.
function MP = MaxPowerSolver(ElectricalData)
Power = ElectricalData(:,2).*ElectricalData(:,3);
MP = max(Power);
end
