Chrissy,

I think that you could use the SUMPRODUCT function to calculate the VAT, but
you would have to change your layout slightly.

Insert a new row 2, and in that row for the columns where the VAT applies,
put the 17.5%, and in the others, put 0.

Then you could usethis formula for prices in row 3:

=SUMPRODUCT($A$2:$J$2,A3:J3)

and then use

=SUM(A3:J3)

to get the subtotal, and

=SUMPRODUCT($A$2:$J$2,A3:J3) + SUM(A3:J3)

to get the overall total, with VAT included.
