Constraints between an integer and multiple choices

Support
1

Hi everyone,
I am having a problem like this: I want to put a constraint between an
integer input and a choice in multiple choice question.

Q1. How much do you spend on food everyday? _________

Q2. Please select the range ?

a. Less than 10usd
b. Between 10usd and 20usd
c. More than 20usd

I want to put a constraint that warn the surveyors in case they input 50usd
and select a or b. Is there anyway to do that.

Thank you very much.

Hi, Tony.
Try this (assuming that your Q2 is select_one question):
put the following expression
( .='a' and ${Q1_name}<10 ) OR ( .='b' and ${Q1_name}>=10 and
${Q1_name}<=20 ) OR ( .='c' and ${Q1_name}>20 )
in the constraint column of Q2
Note that in this expression, "." is put for ${Q2_name}.
Hope that helps.
Best,

Hello !

I am having a problem like this: I want to put a constraint between an
integer input and a choice in multiple choice question.
q1. How much do you spend on food everyday? _________

q2. Please select the range ?

  1. Less than 10usd
  2. Between 10usd and 20usd
  3. More than 20usd

I want to put a constraint that warn the surveyors in case they input 50usd
and select 1 or 2. Is there anyway to do that.

I just copied that I faced the similar case and I follow as given instruction using the xls syntax “(q2='1' and ${q1}<10 ) or (q2='2' and ${q1}>=10 and q2=2 and ${q1}<=20) or ( q2='3' and ${q1}>20)” BUT I could not get success so could you please help me to make right syntax…

Thank you very much.

Hi @debu_odk
I think it should be (selected(., 'q2a') and /data/q1 < 10) or (selected(., 'q2b') and /data/q1 > 10 and /data/q1 < 20) or (selected(., 'q2c') and /data/q1 > 20)
look at the xls file and the form:
test.xml (1.4 KB)
test.xlsx (7.6 KB)

It works well if you use this form in Collect app I don't know why it doesn't work in Enketo preview and I'cant help because I am focused only on ODK Collect. Do you want to use this form in Collect or Enketo?

Dear Grzegorz,

Thank you very much for your kind response. I tried in Kobotoolbox...

in that case you should report this fact to Kobotoolbox as I said it's ok if I use the Collect app.
