MS Access DB Query return always null

Hello,

I have a MS Access database where there are some queries. The query that i want to use have 2 parameters, as you can see below.

The problem is that all the time, the output is only the header of the table. Mention that if i run it manually there are rows in the selection.
I also use “Execute query” on other queries from the Access DB and i have rows selected.

Any thoughts ?

Thank you,
Madalin
