    Hi, is it possible to change the value of radio select box based on another (previous) radio select result? Many thanks.

    This is a re-post of a comment on How to Pass Field Value to Another Field?

    Hi Friend,

    If I understand your requirement correctly, you want to change input values of radio button. It is not possible to change the values of radio button

    However you can use our dynamic dropdown widget alternatively. Basically, by changing the next dropdown option based on previous dropdown.

    Here is the link :


    Let us know if you need further assistance with the feature.

    Hi, I just discovered it *is *possible to change the value of the radio
    button using a bit of Javascript injection.
    An example here is:
    If you select *The presenter is a: Non-student,* then the *Preferred
    session* automatically selects *Concurrent only *option.
    For your information I did this by inserting
    = true* into *Preferred session* in the Conditions wizard.
    Maybe you want to update the manual to include this hidden functionality?
    Cheers, Richard

    Hi again,


    Thanks for the suggestion -

    I've tried dynamic dropdown widget, however it has a serious bug in Firefox - any other javascript code stops working on that page (e.g. the Previous / Next page buttons, the accordion box stops expanding / thrinking).


    Could you please get your engineers to fix the bug asap? Many thanks.
