gd_add_listing short code not work in php

we have using “add listing Shortcode” within another plugin on php but it’s not working.
like this-
<?php echo do_shortcode(‘[gd_add_listing listing_type=gd_event]’); ?>

we are trying to display “add listing” within another plugin “user dashboard”.

but when I click on “add listing” it is not working.

And when I used only “gd listing” its working correctly.
like this-
<?php echo do_shortcode(‘[gd_listings post_type=”gd_event” post_author=”current_user”]’); ?>

so why “add listing” shortcode not work properly.
