Hi Is there a way if i have a question with multiple answers and one of them is (none). Now is there a way if (none ) is chosen, the other choices can't be chosen. I do not want to use the constraints to just remind the person. I mean the one who chooses will not be able to put a mark on other choi…

I can see two options: Use constraint to force correcting an answer Or you can treat such an answer as 0 every time none is selected (no matter it's only none or none + something else)

You can skip/hide such a question using relevant if it is satisfying you.

test.xls (42 KB) What i meant is if you see in the excel test there is a satisfaction question. If the respondent chooses (not satisfied), then the first two choices will be unmarked automatically, so that the calculation will be correct. I mean the first question. Is there a formula for that and n…

test.xls (42 KB) I think in this sheet it is clearer. I was just wondering if there is a way the respondent while selecting the available assets, he might select all of them and so the calculation will be incorrect. I mean he/she might select (tables, chairs and none) and the same time and the scor…

It will be incorrect and that's why I asked why you use select_multiple and another question is could you give a few examples of the expected result, I mean from your calculation.

test.xls (42.5 KB) Here you find an example. What if the respondent chooses (none and tables and chairs). What i wanted to know if there is a formula to write to prevent him/her from selecting two contradictory things.

Hi and welcome, @Mosab_English ! Please be sure to post a new topic if you have a new question. If you think a topic may be related, please link to it rather than responding to the topic. A constraint is exactly what you want in this case. A user will not be able to save the form until a constraint …

[image] LN: if(selected(., '0'), count-selected(.)=1, count-selected(.)>=1) I think count-selected(.)>=1 will effectively make the question mandatory - it has to have an answer. Might this be better? if(selected(., '0'), count-selected(.)=1, true())

[image] Xiphware: effectively make the question mandatory - it has to have an answer. That's correct. With a 'none' option blank should probably not be allowed. What's the difference between 'none' and blank?

If the intention is that question must be answered (ie mandatory), I'd probably do that via required='true()' - which will then be appropriately displayed in the UI (eg prefixed with '*') - rather than obfuscating it via a constraint='...' :grin:

If user selects "none" in multiple select, prevent selection of other options
