percentage calculation

Can anyone help please? Report Gross Grand Total and Sales tax Total are off
by a penny or 2

The amounts are being generated by the
sum expression below that calculate unitprice and salestax so users only
need to put the unit price of the item in the Order Details Table. The
line
totals in the report seem to calculate and display properly but the grand
totals are off by a few pennies. The data type for unit price and sales tax
rate is set to currency and 2 decimal places and will not allow input mask
changes. The Main Report Query gross Order Total shows a number like
667.3768 Thanks

In Report Detail I have Gross Order Total and Sales Tax Total which
seem to
calculate fine...I think. The calculations are incorrect when I Sum
those 2
in the Report footer. This is where I am seeing it off by 1 or 2
pennies.

I did not go through it all but it appears you are applying the sales tax to
each item then totalling.
I do believe you need to total and then apply tax to total.

Hi Karl, thanks for the reply. In my report, all of the line totals that I
have applied the sales tax rate to are correct. It is when I try to sum the
gross of all the line totals where the problem starts. The thing I am unable
to understand is why it is only off by a penny. Keep in mind, I know just
enough about Access to get myself in trouble :) Anyway, hopefully if you
take a look at the rest of the post it will make more sense as to the
solution to my problem. Thanks again.I
