seperating the salestax field in the ACCESS XP's wizard gen. orderentry db [will pay $ for a fix]

I'm using the Order Entry DB that the Access XP wizard creates for you.I'm a novice user and the db is perfect for what I need,

EXCEPT it only has one field for Sales Tax and I need to have two custimizable fields for sales tax.

I've tried adding another field but everything gets messed up because theres queries going on between the subforms and yada yada, this is where i get lost.


Would someone be able to point me in the right direction?

Or could I pay someone a small fee via paypal to make this one modification to my db?


thank you!!
