I'm summing a large column that varies in length depending on the data I've
pulled in. At the mo, I have set up the last cell of the sum to be
ridiculously large, A65000 say. When I calculate it takes an age (although
this may be due to other things that need to update) - would it be
significantly quicker to make it a sumif not blank function on the column.
Or is there another quicker way. Any help would be great as there are only
so many cups of coffee I can drink whilst waiting!! :o)
