Custom validation for multi select question option

Hi everyone,

I have a survey where I ask participants the following questions: 

On the last question (Q14 = QID32), I want the option 'Yes' to be selected only if in the previous question (Q13 = QID31 the 'Name' and 'Company' fields are filled in. I tried to set up a validation rule but was not able to set one for the response option only.

Tried the following JS, but it doesn't work. Does anybody know how can I solve this?

Qualtrics.SurveyEngine.addOnload(function() {
    // Get the values of Name and Company fields from the previous question
    var nameValue = "${q://QID31/ChoiceTextEntryValue/1}";
    var companyValue = "${q://QID31/ChoiceTextEntryValue/4}";

    // Get the Yes option element
    var yesOption = jQuery("#QR~QID32~1");

    // Get the error message element
    var errorMessage = jQuery("<div>Please provide your name and company above.</div>");

    // Check if Name and Company fields are not empty
    if (nameValue.trim() !== "" && companyValue.trim() !== "") {
        // Enable the Yes option
        yesOption.prop("disabled", false);

        // Remove any existing error message
        errorMessage.remove();
    } else {
        // Disable the Yes option
        yesOption.prop("disabled", true);

        // Show the error message
        jQuery("#QR~QID32").append(errorMessage);
    }
});

Thanks in advance!
