Hi,

The following code should do the job.
It will check the box based on a true or false value from a calculated value control.
This happens on form load and then on value change.

 

NWF.FormFiller.Events.RegisterAfterReady(function () {

    function syncCheckbox() {
        var val = NWF$("#" + MyCVID).val();
        if (val === "true") {
            NWF$("#" + yesNoControl).prop("checked", true);
        } else {
            NWF$("#" + yesNoControl).prop("checked", false);
        }
    }

    syncCheckbox();

    NWF$("#" + MyCVID).change(function () {
        syncCheckbox();
    });
});

Hi SImon,

Thank you for your response. 

Just want to clarify on where I can put the Yes/No control in the code? I see you have for the Calculated Value which is the “MyCVID”, how about a reference to the yes/no control field?

Much appreciated.

I tried to code but it is not working, please see result screenshot. The true that was circled was the result of my calculated value and for some reason the Initial Freight checkbox was not mark.

Hi ​@aorellano,

You also need to assign a Client ID JavaScript variable name to the checkbox.
Please see my example form attached.
