how to setting attributes for product's option?

hello Zencart expert

I try to set up some option for my production
ex:

Add (+ $$$)
Add ( free)
subtract ( - $$$)
subtract ( free)
modify ( + .$$$)
modify ( free)
select size
select color
etc .....

i have read from doc and FAQ about attributes setting but i am totally confused

everyone can guide me (step 2 step) how set it up live ex. above

thanks for advance and any help

Best regard,

Well, thanks for reading my question ..... i figured it out

But, i really want to say "thank you very much to Zencart team who worked so hard for us" all you guy ... very well done a free stuff that i never seem on internet
it's very wonderfull world
from the open source code to a mode and template

so, allow me to share some that i got (2 weeks) into the attributes session (for admin)

As someone or acticles already mention the part which required for setting up it

1. going to Admin -> Catergory -> ... option name
   in this step just simple given a name for the option you decide for (ex: Size)
2. in the same page click a option value buttom
   select the option name that you just done on a step 1 and assinged for it a option (ex: Small or large or default size) do each/ time)
3. then (the same page) click on Attributes Controller buttom
   and point it toward you product (do it one by one)

you also can edit it such as add $$$ or the other option like discount or %off ... etc.

that's all .... N-Joy! a new wonder stuff off Zencart Team

Once again thank you very much all of you who work for this Script ......
