Hi,

May I request for assistant on how to make a scoring in my quiz application.

This is my code in my quiz application.

/*Stored answer value*/
 
ForAll(
    GCGIntranetQuizGal.AllItems,
    Collect(
        colRadio,
        {
            Radio: ThisRecord.Radio4.Selected.Value,
            Questionss: ThisRecord.QuestionNumber
        }
    )
);
 
/*Set the right answer*/
 
ClearCollect(
    colCorrectAnswers,
    {
        Question: 1,
        CorrectAnswer: "EIMS"
    },
    {
        Question: 2,
        CorrectAnswer: "MRRS"
    },
    {
        Question: 3,
        CorrectAnswer: "DIRECTORY"
    }
);
 
/*Verify the if the answer of user is equal to right answer.*/
 
ClearCollect(
    colResults,
    ForAll(
        colRadio,
        {
            Question: Questionss,
            UserAnswer: Radio,
            CorrectAnswer: LookUp(
                colCorrectAnswers,
                Questionss = ThisRecord.Question
            ).CorrectAnswer,
            IsCorrect: If(
                Radio = LookUp(
                    colCorrectAnswers,
                    Questionss = ThisRecord.Question
                ).CorrectAnswer,
                true,
                false
            )
        }
    )
);

Hello,

Please refer to the code below for scoring.

I have highlighted my added code in bold.

/* Store the user's answers */
ForAll(
GCGIntranetQuizGal.AllItems,
Collect(
colRadio,
{
Radio: ThisRecord.Radio4.Selected.Value,
Questionss: ThisRecord.QuestionNumber
}
)
);

/* Set the correct answers */
ClearCollect(
colCorrectAnswers,
{ Question: 1, CorrectAnswer: "EIMS" },
{ Question: 2, CorrectAnswer: "MRRS" },
{ Question: 3, CorrectAnswer: "DIRECTORY" }
);

/* Verify if the user's answer is correct and calculate score */
Clear(colResults); // Clear previous results
Set(varScore, 0); // Initialize score

ForAll(
colRadio,
Collect(
colResults,
{
Question: Questionss,
UserAnswer: Radio,
CorrectAnswer: LookUp(colCorrectAnswers, Question = Questionss).CorrectAnswer,
IsCorrect: If(
Radio = LookUp(colCorrectAnswers, Question = Questionss).CorrectAnswer,
true,
false
)
}
);

/* Update the score */
If(
Radio = LookUp(colCorrectAnswers, Question = Questionss).CorrectAnswer,
Set(varScore, varScore + 1) // Increment score if correct
)
);

/* Display the total score */
Set(varFinalScore, varScore); // Store the final score for display

Hi

I have updated your colResults code to include a Score column, 1 if the answer is correct otherwise 0. At end we can do a Sum of the column to get the final score.

ClearCollect( colResults, ForAll( colRadio, { Question: Questionss, UserAnswer: Radio, CorrectAnswer: LookUp( colCorrectAnswers, Questionss = ThisRecord.Question ).CorrectAnswer, IsCorrect: If( Radio = LookUp( colCorrectAnswers, Questionss = ThisRecord.Question ).CorrectAnswer, true, false ), Score: If( Radio = LookUp( colCorrectAnswers, Questionss = ThisRecord.Question ).CorrectAnswer, 1, 0 ) } ) ); Set(varFinalScore, Sum(colResults, Score));

Hi Niranjanbabu Chakali - Your approach will work but I think you will need to wrap your "Update the score" code in a ForAll(colRadio to make it work for all questions.

ForAll(colRadio, If( Radio = LookUp(colCorrectAnswers, Question = Questionss).CorrectAnswer, Set(varScore, varScore + 1), // Increment score if correct false ))

Hope this helps.

Kind regards,

Nandit
