Cross-table then concatenate producing inaccurate results

Dear Qlik Community,

I hope this finds you well. I am currently preparing a school app and the section concerning 'weekly quizzes' is producing inaccurate results. I have three separate tables for three subjects (arabic, math, english). Each table was crosstabled to create a unified date field then concatenated to one another to form one 'weekly quiz table'. Please find enclosed the script:

[weekly quizzes pre school math]:

Crosstable ([Date], [scoremath],4)

LOAD

[الرقم التسلسلي] AS [preschool.الرقم التسلسلي],

[الاسم] AS [preschool.الاسم],

'weekly quizes prescohol' as flagpreschool,

    "43034",

    "43041",

    "43062",

    "43080",

    "43083",

    "43088",

    "43097"

Drop table [weekly quizzes pre school English];

Once loaded into one table, when I create a table or any other visualisation in the front end - I am getting the exact same scores for arabic, english, math. Same averages...same numbers even though each subject has different grades. I am not sure what the problem is. I checked the data source and everything seems normal. When I look at the scores themselves (without aggregations) (scoreenglish,scoremath,scorearabic) they are in date format in the front end (all the year 1899). I tried converting them to num but I still get the same results for each subject.

Any help would much appreciated. Thank you for your support

Best,

Mohammed

Re: Cross-table then concatenate producing inaccurate results

Dear Sunny,

Thank you for your message. The actual problem is with the following fields:

scoremath

scorearabic

scoreenglish

these fields represent quiz grades and for some reason they are identical for each subject. When I review the data source it shows that the students score very differently in each subject but in Qlik sense, no matter what dimension I filter by the grades of each subject are identical to one another.

Best,

Mohammed

Re: Cross-table then concatenate producing inaccurate results

I have tried to just include 1 table (the math one) and the scoremath field still includes dates for some reason even though the values in the datasheet are all numbers. It is a mixtures of dates and numbers and I think this might be one of the reasons why the scores for all subjects are the same:
