attribute error when adding to cart

[newagekat]

Man, this is one busy forum.

I spent the last few hours reading through the archive for attribute. Linda, you rock.

FACTS:

currently using v1.3.0.1, recently installed improved attribute contribution

client sells wrought iron balusters, base price $10
different coating can be applied for extra charge.

I have set priced by attribute in add product to NO
I have created the option names, added values & images, set price to +3.75
set for diplay only YES per FAQ
attribute is free NO
apply discount YES
include in base price NO since the product is Not priced by attribute
attribute required for text NO

CONCERN:
product price is not showing
when i choose an attribute, and add product to cart, I get an error:

Please correct the following:
On the Option for: Powder Coating You picked an Invalid Selection: Silver Vein

QUESTION:
Can someone point me in the right direction. Link to site's test product is: http://customironworks.com/index.php...&products_id=1

Mucho thanks
