Attributes calculating incorrectly

[candycanuck]

My prices are based ONLY on the combination of attributes a customer chooses. There is no static base price.

I have not included a PREFIX when adding some of the attributes, because they are the primary item, while the others are the add-ons. However, this is interfering with the calculations. Anything without a prefix is being subtracted from the price. Is there a way to over-ride this?

 

 

e.g.

Carabiners

Quantity: 150 ($223.50)

 

Note: I do not have a Prefix assigned to this particular attribute. I do not have a - or () on the number when entered in the database.

 

Price at checkout: -$223.50

 

e.g.2

T-Shirt > Vinyl Cutouts

Back Artwork: 1 colour (+$4.00)

Back Colour: blue

Back Colour 2: none

Clothing Colour: Ash Grey-Max 5XL ($5.00) ... Note no prefix on this one.

Front Artwork: 1 colour - Left Pocket Size (+$3.00)

Front Colour 1: none

Front Colour 2: black

Setup: New or modified artwork (+$10.00)

 

Note: All this should add up to $22

 

Price at checkout: $12

(4+3+10-5)=12
