If conditions in Constraint

[Kal_Lam]

Welcome to the community, @kt2630! Here are some examples of using the if-statements under the constraint:

Limiting Choice depending on an answer to the preceding question

Hi @AlexRutto77, You could do the same as outlined in the image below: In the survey tab of your xlsform: [Image 1] In the choices tab of your xlsform: [Image 2] Data entry as seen in Enketo: Constant active when entering the data in a wrong way! [Image 3] Data entry as seen in Enketo: * Constraint passive when entering the data in a correct way!* [Image 4] Reference xlsform: Constraint.xlsx (14.0 KB) Have a great day!

Another one:

How is the syntax for one selected answer where another answer must also be selected in a select_multiple question?

In this case, try this out: In the survey tab of your xlsform: [Image 1] In the choices tab of your xlsform: [Image 2] Data entry screen as seen in Enketo: when a condition is met [Image 3] Data entry screen as seen in Enketo: when a condition is met [Image 4] Data entry screen as seen in Enketo: when a condition is not met [Image 5] Data entry screen as seen in Enketo: when a condition is not met [image] Reference xlsform: Constraint.xlsx (11.4 KB)

And this one too:

Validation condition Pop Up when a wrong choice is selected

Hi @rahul_521, You could do it as follows: In the survey tab of your xlsform: [Image 1] In the choices tab of your xlsform: [Image 2] Data entry screen as seen in Enekto: (when a wrong entry is made) [Image 3] Data entry screen as seen in Enekto: (when a correct entry is made) [Image 4] Data entry screen as seen in Enekto: (when a correct entry is made) [Image 5] Reference xlsform: 2020 08 21 Constraint (If-Statement).xlsx (11.1 KB) Have a great day!

This too:

Restricted options under a repeat group derived from select multiple

Hi @saadiah_ghazali, You could do the same (by making constraints during data entry) as outlined in the image below: In the survey tab of your xlsform: [Image 1] In the choices tab of your xlsform: [Image 2] Data entry screen as seen in Enketo: [Image 3] Reference xlsform: Constaint within Repeat Group.xls (39 KB) Have a great day!

These workaround should help you understand the if-statement and solve your issue.
