Solved! Trying to add combination to a product - I get an error message?

[bongobongo]

Hi.

** UPDATE **

Bahh. After selecting an attribute from the Attribute select I had to click Add button next to
list below the attribute select....

** UPDATE END **

Installed Prestashop on my localhost yesterday to start testing it.
Initially it looked VERY promising.

But now I have gotten a problem related to saving product combinations.

I have created a product.

Then I click the Combinations tab from the product.

Then I select:
Group: Color
Attribute: Black

I do not enter any other information.

Then I click "Add this combination" button

and get this error:

"1 error
you must add at least one attribute"

Does not make much sense to me since I did select an attribute:
I selected "Black" from the Attribute select.

Anybody that can help me with this?

Regards
