2 important questions about Access 2000

Hi Everyone!
Could anyone help me?
I'm trying to create a macro which opens a query which saves certain records from a table into a floppy, and afterwards the macro opens a query which takes the same records that the first one got (without asking the user again) and deletes them.

I have 2 problems:

1. I wrote:
Between DateSerial([forms]![request_delete_records]![start_year_],[forms]![request_delete_records]![start_month_],1) And DateSerial([forms]![request_delete_records]![end_year_],[forms]![request_delete_records]![end_month_],31)
in order to ask the user's criteria through my own form - but the Access ignores it and uses its own default form.

2. How can I tell the deletion query to take its input from the backup query, I mean: How can I take a query's output to be another query's input?

Please help me if you can!
Thanks
