I had a good time, translation

Question

"I wrote, J'ai passe de bons moments" and it was marked wrong. The correct answer was "J'ai eu de...." All the prompt said to do was to conjugate avoir. I don't think there's anything wrong with my answer. Could you please explain? Once again, I'm checking the box that says "Send email notifications of new answers," and I haven't gotten any responses.

Accepted Answer

As with all free-text answers, there are many possible replies, and it is virtually impossible to check for all of them. Just because the given answer is different from what you entered doesn't necessarily mean that your choice is incorrect.
The hint "conjugate avoir" does point in a certain direction, however. It hints at avoir being the main verb of the sentence. In your answer it is only the auxiliary verb to passer.

Answer

Bonjour !
Upon review, this question was indeed awkward, as the best sentence would be to use "passer de bons moments", and here we were testing "avoir". We therefore removed this question to replace it with a better one :) 
Merci encore et bonne journée !
