The Function Point Calculator consists of two separate steps:
   
Step 1 is to fill in a table with estimates for the software
you plan to develop.
   
Step 2 is to answer several questions about your software.
Once both Step 1 and Step 2 are completed, all that is left is to click
on a button and the number of function points for your project will
be calculated.
Both Step 1 and Step 2 are needed to calculate an accurate number
of function points. If you bypass Step 2 (answering the questions)
the calculated number of function points will be incorrect. Bypassing
Step 1 will result in ZERO function points no matter how you answer the
questions from Step 2, so this is not allowed.
If you need any help along the way, look for the question marks.
Clicking on the blue question marks will open up a help window that relates to
the step you are on.
