Require a field based on value changing in another

[Edwin Fuller]

Hi everyone, within the form I created I have a date field called "Expected Completion Date". Whenever the value of the field changes to any other value I would like the next field "Expected Completion Date Change Reason" to become a required field. So basically in order to change the date field you need to provide a reason. Does anyone know how this can be done, possible using a script?

Thanks,

Edwin

Hi Edwin,

Looks like date filter is not applicable in UI policy. Please create a OnChange Client script on "Expected Completion Date" field with below script. Please modify field column names as per your req.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
   return;
   }
   if(oldValue != newValue)
   {
   g_form.setMandatory('u_start_date', true); //Here replace u_start_date with exact field column name
   }
   else
   {
   g_form.setMandatory('u_start_date', false); //Here replace u_start_date with exact field column name
   }

   //Type appropriate comment here, and begin script below

}

Hi Edwin,

Is the issue resolved now?

The script works as intended, but I need a condition. When the field is populated for the first time or there is no previous value then do NOT require the next field
