DLookup(“item”, “inventory” , “Criteria = n”)

  1. The DLookup function returns a single field value based on the information specified in criteria.
  2. Although criteria is an optional argument, if you don’t supply a value for criteria, the DLookup function returns a random value in the domain.
  3. If no record satisfies criteria or if domain contains no records, the DLookup function returns a Null.
  4. If more than one field meets criteria, the DLookup function returns the first occurrence

So, if you are expecting to display all records DLookup will not make it.
