Customfields bug in 2.0.7b

[maketheweb]

In 2.0.6 and 2.0.7b I encounter a problem while using customfields with custom prices. (I use Joomla 1.5.26 btw)

When using custom fields with custom prices, for example Product price: €5,- Option A: €1 and Option B: €2

the price of the final product is always €6,- (€5 + €1), for some reason Option A is always selected even when I select option B

I added the custom fields as cart attribute and everything and the values and prices as follows: Value: Option A        Price: .25  (has to add 25 cents).

Is this a bug? Am I the only one with this problem? Am I doing something wrong here?
