I recently asked a question on SO to which the combination of two separate answers should be the accepted answer, however each answer by itself is not completely really correct. I edited my original question to make it a little more specific to the scenario that was causing me a problem. Once I did this and started testing out users suggestions I discovered that a combination of answers actually solves the issue at hand. Is there any way that this is supposed to be handled to provide an accepted answer?
Well the best thing to do is probably to write your own answer telling how did you combine both answers (telling you took it from Mr.X and Mr.Y). Make sure to include the relevant information from the answers in your answer to make it complete though. You can accept your own answer after a few days.
Making another answer is better because it will contain the missing information as how to combine the information from the two other answer and thus helping users finding this question in the future. Also, accepting only one of the two answer could mislead other users.
Make sure to upvote the two answers that were useful to you.
