# EditTrainingQuestionInput

input type

Edit-input for a TrainingQuestion. Every field optional, at least ONE required; supplied fields REPLACE prompt, options (WHOLESALE), correctIndex, explanation, stepN and/or caption — at least one; when only one of options/correctIndex moves, the index is checked against the stored options; courseKey and source never move.
