Newbie Needs Help with Attributes Manager

[ladyk]

Hi everyone;

New to Zen Cart here and have been playing and learning the in's and out's on my new site set up to sell. I got all the Option Names and Values set up and sorted.
Now I am trying to figure out Attributes Manager. This is what I'd like to be able to do.
I sell dresses and need to do a percentage increase on certain sizes. 5%, 10%, 15%, 20%, 25% and 30%
I Google searched for help and found some links to the forum here that I've tried. The one to do 10% is to put in Price Factor: Offset 0.9000 in first box and 1.0000 in the next box. The amount comes up right but it is - instead of +
Tried reading more support threads but just got more confused LOL
Could someone be so kind as to walk me through how to set this up?
Also another question ..... All the attributes will be the same for all the dresses as far as color and size. Is there a way to "check" something so that the attributes go to all the products at once, or do I need to put them in by individual product? I really hope that made sense
Any help would be most appreciated and thanks in advance.

This works as:
(Product Price x Price Factor) - (Product Price x Offset)

If you use:
Price Factor: .90
Offset: 1

You get a negative number ...

If you use:
Price Factor: 1
Offset: .90

you get a positive number ...
