Have you got an individual price set up for that product, as a basic price?

I have some items that have prices effected by attributes, but have set the item up with a standard price first, then added the attributes afterwards. The attributes then add the difference in cost for each extra function/feature/colour/size or which ever you need. I did this by adding the attributes to the product after it was made, then editing the attributes to add extra cost and weight as appropriate.

It could also be that you have the 'Product Priced by Attributes:' check box set to yes in the product page in admin. Iirc, when you do this, the item is priced only by attributes.

I have that check box set to no, then use a basic price in the product set up for the cheapest option. Then I use the attributes only to add the extra cost/weight for each other choice as appropriate.
