To specify numeric criteria for an operation, you supply a numeric value as part of the string expression that forms the _criteria_ argument.
Suppose that you are performing the DLookup function on an Employees table to find the last name of a particular employee, and you want to use a value from the EmployeeID field in the function’s _criteria_ argument. You could construct a _criteria_ argument like the following example, which returns the last name of the employee whose EmployeeID is 7:
“vb
=DLookup("[LastName]", "Employees", "[EmployeeID] = 7")
“
