affiliate program script change

[manula]

Hi there,

I'm going crazy over this piece of code. I'm a newbie of php and I can't get my head around this.
I know what I'm trying to do is quite simple but nothing I've tried works. Perhaps someone out there can point me in the right direction!

This is a an extract of a script I own and have the right to change. The behaviour I'm trying to change is:
- currently - website members do not earn any points or cash commission for new FREE members they sponsor.

- I want - website members to still earn any points or cash commission for new FREE members they sponsor.

As you can see below the script has 4 membership levels. The variables we need to work on are 'AFF_RATES_FOR_LEVELS' and 'AFF_POINTS_FOR_LEVELS'

Here's the code. Thanks in advance for trying to help.
Regards
