warning: reset() expects parameter 1 array, string given in /home/betaacademyofflo/public_html/wp-content/plugins/woocommerce-bookings/templates/booking-form/date-picker.php on line 54

warning: variable passed each() not array or object in /home/betaacademyofflo/public_html/wp-content/plugins/woocommerce-bookings/templates/booking-form/date-picker.php on line 55
