error saving a struct

Hi. Anyone know why this gives an error? I'm using MATLAB R2017b

A = [];
A.days ={'Monday','Tuesday'};
A.debt = randn(5);
if strcmp(class(A),'struct') && isscalar(A)
    save('A.mat','-struct',A)
end
Error using save
The argument to -STRUCT must be the name of a scalar structure variable.
