Are you using the shortcode or the function call to embed your form, or perhaps a widget?
If you're using a shortcode, make sure your theme has the wp_head() function call in the header.php file and the wp_footer() function included in your footer.php file. Gravity forms uses those functions to add the necessary scripts for conditional logic.
When using a Gravity Form in a sidebar widget or embedding it anywhere using the function call, you need to manually enqueue the scripts and CSS by placing a short script block in your theme's functions.php file.
wp_enqueue_script("gforms_ui_datepicker", WP_PLUGIN_URL . "/gravityforms/js/jquery-ui/ui.datepicker.js", array("jquery"), "1.3.9", true);
wp_enqueue_script("gforms_datepicker", WP_PLUGIN_URL . "/gravityforms/js/datepicker.js", array("gforms_ui_datepicker"), "1.3.9", true);
wp_enqueue_script("gforms_conditional_logic_lib", WP_PLUGIN_URL . "/gravityforms/js/conditional_logic.js", array("gforms_ui_datepicker"), "1.3.9", true);
wp_enqueue_style("gforms_css", WP_PLUGIN_URL . "/gravityforms/css/forms.css");
Without this, the conditional logic scripts, datepicker script, form CSS and other elements needed for the full form functionality aren't loaded.
