product has 4 different prices

[adelrami]

My product ( Tour package) has 4 different prices, according to room type and Hotel Grade.
I successfully added attributes and they work, but my problem is that i have to put a price for the product itself in order for the attributes to show. how can i override this.

What i am trying to reach... product price hidden
attributes appear
customer select his package from the attributes and check out

I am using joomla 1.5.20
Virtumart 2.0.2

any one can help with this?
