Subtotalling variable data

[djcfisher]

Hi there. In the attached sheet I am trying to return a Total in cell H5 (sheet 2) based on the following steps:

1. Calculate no. of units in sheet 1, column L where ("£1.25" = 1 unit and "£2.50" = 2 units)
2. Subtract units where there is a value in sheet 1, column M greater than zero. For example, row 13 in sheet 1 would total 1 unit ("£1.25" in L13 = 1 unit and there's nothing above zero in M13); row 20 would total 2 units using the same logic; but row 35 would be zero units as M35 = >0.
3. Add the whole lot together to return my Total in sheet 2, H5.

The problem I'm having is with getting it to subtract the appropriate number of units when it sees a value above zero in column M - i.e. subtract 1 unit when L*=£1.25 but subtract 2 units when L*=£2.50.

Any help would be appreciated.

So in row 35 it should subtract one unit from the eggs even though there is a 2? The way you use your "Holiday this wk?" column is unclear. It could aid in the solution if better understood.

Hi Bongaan, sorry for the confusion. The characters in Column M have no significance (well they do have significance, but for a purpose unrelated to this thread). Basically, if any number above zero appears in Column M, whatever it is, for these purposes it just means the same thing - the customer is on holiday so does not want their eggs. What I'm trying to get Excel to recognise in the totalling is that, if column L is £2.50, the customer buys 2 boxes of eggs; if column L is £1.25, the customer buys 1 box of eggs. If anything appears in column M (showing that the customer is on holiday), I want Excel to subtract the correct number of boxes (1 or 2) from the total in cell H5 (sheet 2). Does that make sense? Thanks!

Thanks, now better understood, this should do it: =SUMIFS('Sheet 1'!L:L,'Sheet 1'!M:M,"",'Sheet 1'!S:S,"")/1.25

the formula reads: Sum those egg prices in L which have no value in M (Customer not on holiday) and which also have no value in S (customer haven't left).

Great solution, thanks! Just one remaining question if you don't mind my ignorance. If I want to filter Sheet 1 (in this case using Column P to filter only by customers due a delivery this week), how do I get the calculation in sheet 2 cell H5 to be based just on the visible rows? Thanks once again for your help.

It's unfortunately only the subtotal function that "take note" of filtered results, so you will have to combine subtotal and sumif somehow. There is a solution to that, but unfortunately not in my league. Google "sumif and subtotal". I unfortunately do not have the time now to figure it out myself, sorry.
