Hello

I have written a fairly big spreadsheet linking through the pages with SUM,
SUMIF and SUMPRODUCT formula's

What I am now finding is that when I update one page it doesn't update the
rest, even if I am only typing in a figure to the SUM function.

I have check and the calculations function is on automatic.

is there a fix or something that I could run to make sure that all the
formulas are working correctly.

thanks
