Try to at least provide a little effort on this. If it's wrong, it's wrong but give it a try first.

Start big -- move towards details.

Requirements are probably the most important part of software design. One needs to know what we are building before we can build it.

Start with the big picture. Identify basic areas and then begin to narrow down to line items.

For example your application will definetly have requirements regarding -- a database, user interface.

For the database as yourself questions like:

What kind of data will they need to keep track of?
Will there be a need for reporting/analysis?
How much data will there be?
Is the database external (MySql, Oralce etc,) or integrated?
Is there are need for archiving?
and on and on.

These can each be broken up to define in more detail what is meant. For example under reporting you might have:
Need the ability to view a report of weekly/monthly/quarterly earnings.
Need the ability to rank item's popularity by sales.

remember requirements are about the business needs not (normally) the implementation details. IF you find yourself talking about buttons, and fields, graphics, particular object or functions etc. you are probably going into too much detail.
