HELP! ? On ovulation test

Emily
What does this mean? I took my test in the afternoon after work, the ovulation test had a question mark.  So I read the directions and it said that an error had occurred. It told me to retake the test and it would fix itself basically. When I read to the test, twice, both times it had a question mark. What am I doing wrong?? Anyone else experience this? It is First Response brand.
