Rate a Microsoft Forms Survey with choice questions using LOOKUPVALUE

[calerof]

Hello,

I'm trying to rate a survey made with Microsoft Forms with choice questions using the LOOKUPVALUE function. 

I made a sample data file and it's working, but in my actual data it's not, I receive the error message:

"A table of multiple values was supplied where a single value was expected".

1. Sample data

I have three tables in this excel file:

• Questions, including only 5 questions with 5 choices each, i.e.
  • Always, Most time, Some time, Almost never, Never.
• Rating_table: Valuation of answers, each question has its own valuation, as follows (I unpivoted it in Power Query):
• Answers of two survey participants for this sample:
• 

After cleaning the data I try to value each answer with this code:

Answer value = 
LOOKUPVALUE(
    Rating_table3[Value],
    Rating_table3[Option],
    Answers1[Answer],
    Rating_table3[Question number],
    Answers1[Question Number]
)

This works fine:

PBIX file

2. Actual Data

Same procedures. Here are my files:

Answers

Questions

Valuation table

Code:

Respuesta Valor = 
LOOKUPVALUE(
    Tabla51[Valor],
    Tabla51[Opcion],
    Respuestas[Respuesta],
    Tabla51[Item],
    Respuestas[Pregunta Num]
)

PBIX file

I'd really appreciate your support.

Best regards,

Fernando

Hey,

first things first, thanks providing a great explanation and all the sample data you provided as well.

As I'm currently running out of time I will provide just this link: https://www.daxpatterns.com/survey/

The article explains how survey data can be analyzed using a tabular model.

Regards,

Tom

Hi @calerof ,

When you use the lookupvalue, you condition may filter more than 1 rows, you can test it like following.

if you just want negativa value, we can use the following formula.

Respuesta Valor =
VAR t =
    CALCULATE (
        COUNTROWS ( 'Tabla51' ),
        FILTER (
            'Tabla51',
            Tabla51[Opcion] = [Respuesta]
                && Tabla51[Item] = [Pregunta Num]
        )
    )
VAR result =
    IF (
        t = 1,
        LOOKUPVALUE (
            Tabla51[Valor],
            Tabla51[Opcion], Respuestas[Respuesta],
            Tabla51[Item], Respuestas[Pregunta Num]
        ),
        VAR s = "Negativa" -- or other conditon you want
        RETURN
            MAXX (
                FILTER (
                    'Tabla51',
                    Tabla51[Opcion] = [Respuesta]
                        && Tabla51[Item] = [Pregunta Num]
                        && Tabla51[Expresividad] = s
                ),
                [Valor]
            )
    )
RETURN
    result

or jump the judge, just use the maxx/minx function.

BTW, pbix as attached.

Hi @v-lid-msft ,

Thank you very much for your response and the time to review my model. After reviewing your solution and rechecking my data, you made me realize that in my Valuation table (Table51) I had a duplicated record, i.e. question # 54, thus producing the error in the LOOKUPVALUE calculated column. After eliminating the duplicated value the code works smoothly:

Respuesta Val = 
LOOKUPVALUE(
    Tabla51[Valor],
    Tabla51[Opcion],
    Respuestas_valuadas1[Respuesta],
    Tabla51[Item],
    Respuestas_valuadas1[Pregunta_Num]
)

It's always great to have the Community's support.

Cheers,

Fernando
