I have a problem

After I had submitted the solution for the Sum of two numbers problem, my grade was 0 of 3... I have a problem with that because I think my program is good enough... Here is the code:
program suma;
var
M, N, S: integer;
label
PrviBroj, DrugiBroj;
begin
PrviBroj:
write('Uneti prvi broj (0-200): ');
readln(M);
If (M < 0) OR (M > 200) then
begin
writeln('Pogresan unos - broj mora biti izmedju 0 i 200!');
goto PrviBroj;
end;
DrugiBroj:
write('Uneti drugi broj (0-200): ');
readln(N);
If (N < 0) OR (N > 200) then
begin
writeln('Pogresan unos - broj mora biti izmedju 0 i 200!');
goto DrugiBroj;
end;
S:= M + N;
writeln('Suma brojeva je: ', S);
end.
Can someone tell me why they aren't accepting my code?

You must write ONLY what the task asks you to write. No additional texts such as "Unesi broj", etc.

OK, thanks... :)
