Laravel 4.2 Sync multidimensional array in pivot table

These are my tables with relation ship functions.

issues table

id
issueName

Every Issue has multiple question

In Issue.php model

public function questions() {
        return $this->hasMany('Question','issueID','id');
    }

questions table

id
issueID
questionText
questionScore

every question belong to an Issue, it has its corresponding score

In Question.php model

public function issues() {
        return $this->belongsTo('Issue');
    }

Using radio input I am selecting a question for each Issue, and geting an array of questionID, score which is intended to save in the pivot table.

assessments table

id
totalScore

in Assessment.php model

public function scores() {
            return $this->belongsToMany('Question','assessments_question_score','assessmentsID','id');
        }

in Question.php model

public function assessments() {
            return $this->belongsToMany('Assessment');
        }

assessments_question_score table

id
assessmentsID
questionID
score

when I am trying to sync questionID, score to assessments_question_score table using

$assessments = New Assessment;
...
...
$assessments->save();
$assessments->scores()->sync($questionIDscore);

but it is not working, Is it wrong to sync multi dimentional array in sync or something else I am missing? How can I accomplish that?

Assessment.php

public function questions() {
   return $this->belongsToMany('Question','assessments_question_score','assessmentsID','questionID');
}

Question.php

public function assessments() {
    return $this->belongsToMany('Assessment','assessments_question_score','questionID','assessmentsID'););
}

Then you can connect questions to an assessment like this:

$questionIds = array(2,5,6);

$assessment = new Assessment;
$assessment->save();
$assessment->questions()->sync($questionIds);

Questions with id 2, 5 and 6 are then connected to the assessment.

To get the score of the first question:

$questionScore = $assessment->questions()->first->questionScore;

To get the totalscore of all questions:

$totalScore = $assessment->questions()->sum('questionScore');

To get the average score of all questions:

$averageScore = $assessment->questions()->avg('questionScore');
