Carry out a cross-cast check in excel

[liamdocherty]

2.1Carry out a cross-cast check(on the funding worksheet – Total Funding) that uses secondary columns to perform the same calculation but in a different way to ensure your spreadsheet shows it is accurate.

How can I perform a cross check in my total funding that uses secondary columns to perform the same calculation but in a different way to ensure your spreadsheet shows it is accurate?

Thanks,

There aren't too many "secondary columns". The only thing I can think of would be to compare the total of Column H with a SUMPRODUCT of the individual columns.
Something like:

SUM(H5:H24) = SUMPRODUCT((E5:E24*F5:F24)+G5:G24)

And, you could expand the range a bit if you weren't sure how many lines there were:

SUM(H5:H30) = SUMPRODUCT((E5:E30*F5:F30)+G5:G30)

Hi,

thanks for the response. Where do I place this code formula?

You could put it anywhere, really. The formulas are not dependent on the location.
I only have a picture rather than the actual data, so here is a complete example (only a few rows) with the checksum at the top.
You would know if something was wrong if the two totals at the top don't match at any given time:

	E	F	G	H	I
Sum of Totals
Checksum
Course Cost	Attendees	Basic	Extra	Total
