check box array to dynamically fetch detail records

Hello,

This is on forms 10g , Oracle EBS r12.1.3

I have a business need that can be described in the bullet points below.

1. Under tools , there is a special menu item called "View/Edit Selection criteria".   This is a form with multi record checkbox and text items.
2. User checks values as "checked", and responds by hitting OK button.
3. Depending on number of selections checked, the main form that is open should fetch number of records. For e.g if there are 5 records checked under special menu, then it may fetch 50 rows on the main form.  If there are 10 records checked, then it may fetch 100 rows and so on.
