    How do I prevent multiple answers being selected in a matrix question?

    Asked by ConciliumGroup on August 15, 2012 at 08:51 PM

    I notice that if I answer multiple answers in a single question for a matrix set there is no way to setup an alert notifying me of this mistake. How do I prevent a respondent from inadvertently answering a question multiple times? Right now Jotform will collect and display all answers given even if only one option should be selected and not multiple.

    You can modify your matrix in several ways. You can add or delete colums. You can also choose input types.

    Please choose the radio button input type instead of the Text Box one. This way I think you will be able to accomplish what you are looking for

    Hi Jeanette,

    Not sure if my question was clearly understood. I am using CHeck Box as an answer option (this would be the same for radio button), and I am looking for a way to limit the number of choices for each question/statement. In other words, I dont want a respondent to select more than one answer option for each question. At the moment JotForm allows multiple answer options which could be a problem when analysing the results.

    Hope this is clearer

    I think I still don't get it, I though you wanted something like this the user will be able to select only one option for each Item

    To disallow selection of multiple answers, you will have to use radio buttons instead of checkbox for your matrix table.

    While editing the form, select the matrix table then click the Input Type button to change from checkbox to radio button.

    Okay I have changed from Tickbox to radio button and that has solved the problem.

    Many thanks.

    Sorry for any confusion
