How can I auto populate email field, when user field filled.

[ND7]

Dear Expert,

How can I proceed with this requirement? Once the user field name is entered, the email field should automatically populate. Please help Thank you so much. Appreciate your help.

did you try putting alerts ?

make sure your back end names of variables are correct  

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }
 
    var user = g_form.getReference('name', userDetails);
    
    function userDetails(user) {
alert(user.email);
        g_form.setValue('email', user.email);
    }
}
