Setting up membership

Setting up membership.
We are planning to use practiscore to manage our members and collect the yearly fees.
We have different membership amounts. It appears that the set a custom price is not working? How do I get this to work?

The membership section is very basic and has limited options.
The custom area basically only lets you choose a different fiscal year start and stop. It does not offer different amounts or different dates for members.
