DLOOKUP is not returning a value - ms/access 2013

I am running a query that needs to compute a value based on one external table. The  Table, named "__parametrosAAP", contains 3 fields for this purpose. A minimum value, a maximum value and a key value, named, respectively, [PopAlvoInf], [PopAlvoSup] and [ClasseAAP].
Depending on a value on the query, [PopPNUD] I need to select a specific record from "__parametrosAAP" and put it in the [ClassePNUD] column.

Thus I have the following query formula:

ClassePNUD: DLookUp("[ClasseAAP]";"__parametrosAAP";[PopPNUD]<=" [__parametrosAAP]![PopAlvoSup]  " And [PopPNUD]>="[__parametrosAAP]![PopAlvoInf]")

But, no matter how, it is always returning null values, in spite the table being correctly filled.

The query is named "sustenta 02 prep" and I am sending the database, just in case.

Can anyone help?
