Make field required in Portal based on value selected in another field

I am using Dataverse/Model driven app but displaying on a Portal.


I have two fields:

myschema_OtherPresentation  - Custom Choice field (Yes, No, Blank) - appears as radio button

myschema_DescribethisOtherPresentation - - Text field


If someone chooses "Yes" for myschema_OtherPresentation, then make myschema_DescribethisOtherPresentation required. Both fields are on the same tab and there is a Next button after this tab.  However, choosing Yes/No does not change a section or tab etc. so I believe I can't use Advanced Form Steps. 


Right now I am using this Javascript but don't know what is wrong with this: 









      $(document).ready(function () {
         if (typeof (Page_Validators) == 'undefined') return;
         // Create new validator
         var newValidator = document.createElement('span'); = "none"; = "myschema_DescribethisOtherPresentationValidator";
         newValidator.controltovalidate = "myschema_DescribethisOtherPresentation";
         newValidator.errormessage = "<a href='#myschema_DescribethisOtherPresentation_label'>Describe this Other Presentation is a required field.</a>";
         newValidator.validationGroup = ""; // Set this if you have set ValidationGroup on the form
         newValidator.initialvalue = "";
         newValidator.evaluationfunction = function () {
            var contactMethod = $("#myschema_OtherPresentation").val();
            if (contactMethod != 669080000) return true; // check if OtherPresentation is not 'Yes'
            // only require DescribethisOtherPresentation if OtherPresentation is Yes.
            var value = $("#myschema_DescribethisOtherPresentation").val();
            if (value == null || value == "") {
            return false;
            } else {
               return true;
         // Add the new validator to the page validators array:
         // Wire-up the click event handler of the validation summary link
         $("a[href='#myschema_DescribethisOtherPresentation_label']").on("click", function () { scrollToAndFocus('myschema_DescribethisOtherPresentation_label','myschema_DescribethisOtherPresentation'); });










Yes value is 669,080,000 in my option set

No value is 669,080,001
