I created a custom field type dropdown in quotes to allow users include a new status value for records, when the field is updated using edit function everything works well; but if using display screen make a double clik in thje check symbol field and change the value appear a message:
Warning : A non-numeric value encountered in /var/www/vhosts/3dproductos.com.co/crm.lamarcgroup.com/modules/Currencies/Currency.php on line 100
even if you dont select any field of the list appear the mesage
