How to setup Wpdisquz User Registration & Login

Sorry forgot to add image attachment.

So I my "open by selector" for the elementor login popup is a[href="#login"]

When I include it to the code provided (exactly as seen below) I'm getting an error message:

add_filter("wpdiscuz_login_link", function ($login) {
return $login . " or <a href='a[href="#login"]'> register</a>" ;
});

Error Message:

Your PHP code changes were rolled back due to an error on line 221 of file wp-content/themes/hello-elementor/functions.php. Please fix and try saving again.

syntax error, unexpected '}', expecting ';'

Am I doing something wrong here? Thank you. 

(I tried adding the changes that you suggested but users will still get the default wordpress login screen)

But I did just see another post with an identical issue https://wpdiscuz.com/community/wpdiscuz-integration/elementor-popup-login/#post-13630

I copied every step in the post but when I get to adding the code the user provided (as seen below) to my function theme I get an error stating

Your PHP code changes were rolled back due to an error on line 219 of file wp-content/themes/hello-elementor/functions.php. Please fix and try saving again.

Do you know what I'm doing wrong here? Thank you. 

syntax error, unexpected '$', expecting variable (T_VARIABLE)

(function($){
    $('.wpd-popup-login-form').on('click', function(e){
        e.preventDefault();
        var popuplink = $('wpd-popup-login-form"]');
        if ( popuplink.length > 0 ) {
            popuplink.each(function(i,e){
                var element = $(e);
                if ( element.attr('href') === 'wpd-popup-login-form"]' ) {
                    element.trigger('click');
                    return false;
                }
            })
        }
    });
})(jQuery);

I dont have a lot of time is it possible we can expediate this ticket and get my issue resolved asap. 

First, instal woody snippet plugin, after create a PHP snippet and clic "Run everywhere" :

add_filter("wpdiscuz_login_link", function ($login) {
return str_replace(" href=", " class='wpd-popup-login-form' href=", $login);
});

After, always in Woody Snippet, create a JS snippet and select "Automatic insertion", in insertion location choose "Footer" :

(function($){
    $('.wpd-popup-login-form').on('click', function(e){
        e.preventDefault();
        var popuplink = $('wpd-popup-login-form"]');
        if ( popuplink.length > 0 ) {
            popuplink.each(function(i,e){
                var element = $(e);
                if ( element.attr('href') === 'wpd-popup-login-form"]' ) {
                    element.trigger('click');
                    return false;
                }
            })
        }
    });
})(jQuery);

So now go to Elementor, modal Windows, and before creating the login form, go to the wheel, at the bottom left, go to advanced and in "Open via selector" put and don't forget the dot before : 

.wpd-popup-login-form

After that put Elementor Connect widget and save.

If you follow that, there's no reason it shouldn't work
