Manipulative Numbers

    I am attemping to complete one of the Erlang sample test exercises. When I try to run my code, I get an odd Erlang error:

    {"init terminating in do_boot",{badarg,[{array,size,1,[{file,"array.erl"},{line,324}]},{solution,main,0,[{file,"/run-CIU10ESE6BCJICS6R3yc/solution.erl"},{line,47}]},{init,start_em,1,[]},{init,do_boot,3,[]}]}}

    This looks like an Erlang configuration problem to me. I'm pretty confident that my code is correct since it runs as expected in my local environment.

    The exercise that I am attempting is "Odd Numbers" and my code is:

    even(X) when X >= 0 -> (X band 1) == 0.
odd(X) when X > 0 -> not even(X).

oddNumbers(L, L) ->
    Odd = odd(L),
    if
        Odd ->
            [L];
        true ->
            []
    end;   
oddNumbers(L, R) -> 
    Odd = odd(L),
    if
        Odd ->
            [L | oddNumbers(L + 1, R)];
        true -> 
            oddNumbers(L + 1, R)
    end.

    Can someone check to see what might be going wrong?

    Thanks
