Chamilo LMS 1.9.4 Custom Modification (in fill in the blanks question type) - repost

I would need a modification in version 1.9.4 of chamilo ([login to view URL]) The modification is in the fill in the blanks question type. The current format of this question type is: Text text text text [answer1] text [answer2] text text [answer3] As you may see it only accepts 1 answer per []. I need it to take more than 1 answer as correct for the same “gap”, for example: Text text text [answer1|this is answer 2] text text [answer3|this is answer 4|answer5] text So if the user types in “answer1” or “this is answer 2” as the answer for the first gap, it will take that as correct. If the user types in something else that was not specified as a correct answer at the time of creating the question, then it should count it as wrong. In my case, most of the times each gap will not exceed 10 possible answers.. but it may in the future. So please take this in consideration. It would be perfect if you can make the amount of possible answers unlimited. If you could get back to me as soon as possible with a price and time estimation it’ll be great. Please take in consideration that I need this as soon as possible. Thanks.
