Hi if the date filled is getting null please send the schema of table or mention the data type of date field. The date field is getting null because you are trying to save improper data types. data type date accept date in yy-mm--dd format and you are giving %m/%d/%Y format due to which it is getting null. Hope it will hepl you.
