Hello there
When I am creating a survey list for inputting numbers, and there is a total as the last question, I want a choice for the users to put the total manually. 2+2 = 4
The user has to put the number 4 for total.
If he puts 5 then there should be a validation error.
How can I do this?
I am attaching a sample survey here.

1. Choice for user to put the total.
2. Validation error when the total is wrong.

Thanks
Babu Ramabadran

Hi, Babu,
1. please do not send a *.lsg (group) or *.lsq (question.
The import of both is language dependent, meaning we have to create a survey first which has the same base language as your file (which we do not know)
So to make our life easier send a whole survey *.lss with only the important questions.

2. You have a lot of errors in your survey.
a. You ask for numbers but use questions of type "multiple short text". Here you have to validate that the respondent really enters numbers.
There is a question type "multiple numeric input".

b. Your equation to calculate the total in the text display is wrong:
Total = Sum(Q1_SQ00.NAOK, Q2_SQ00.NAOK, Q3_SQ00.NAOK)

b.a. I hope you read the manual about the Expression Manager.
Here you read something about curly brackets to use:
https://manual.limesurvey.org/Expression_Manager_-_presentation#Equations
These are missing in your equation.

b.b. You refer to subquestions "SQ00", but you did not declare a subquestion "SQ00".

And where is anything related to your question in this survey?
Where is the users input of the total? And which total?
The total of the three questions?
Okay, then validate the input of this question:
Q4=sum(...)

Again I recommend to study the sample surveys about Expression Manager in the Demo Installation and to read the manual about question types and Expression Manager.
