Receiving 'not enough input arguments' in code

I keep receiving error message on line 4 " not enough input arguements", not sure how to rectify.

function D=areavol(A)
format
D= 0; % where D=parallelogram
if size(A,2)== 2
D=1;    
end

Rank =rank(A); %get rank
[rows,~]=size(A); % get rows

if rows>rank
    if D==1
        printf("parallelogram can't be built.\n")
    else
        printf("parallelpiped can't be built.\n")
    end
    D=0;
    return; 
end

>> areavol
Not enough input arguments.

Error in areavol (line 4)
if size(A,2)== 2

You need

rows>Rank

instead of

rows>rank

MATLAB is case-sensitive. It would be better to have named that variable something that is not a keyword (despite the different case). Then it would have been easier to catch that mistake (or never have made it in the first place).

Also, note that in the editor, MATLAB will have warned you (with a squiggly yellow line) that the variable Rank was never used.
