I really am trying to understand and solve this problem.  When you say enter the "Formula" in the AMOUNT box, what are you referring to?  What formula?  If I have 600 boxes, that is the DESCRIPTION, the cost of each box is 24.95.  I would like to get QB to calculate that one LINE ITEM total cost before I move to the next LINE ITEM.  So if in the AMOUNT box I try to enter 600 X 24.95 it will not even allow you to enter that, no special characters allowed.

My vendor bills look like this:

500       Boxes    @ 24.95

200       Boxes     @   22.95

350       Boxes    @    28.00

The LINE ITEM total is what I'm trying to get calculated.  In the case above I need to pull out my calculator and calculate each LINE ITEM total then enter in the AMOUNT box.  This is needed  rather than just a GRAND TOTAL for the entrie bill because many times we must go back and adjust pricing for one LINE ITEM.  

I hope I've made myself a little more clear on the problem.  I do appreciate any help, as I have had no assistance from QB Help.    Thank you!
