Counting Two Number Sequences

[Necroscope]

Hello all. I hope you can help with this. It sounds simple in my head but I can't figure out the formula!

A1 and B1 have the numbers 100 and 199 in them. (It's a range of 100 ticket numbers.)
A2 and B2 have the numbers 500 and 599. (Another range of 100.)

In C1, I have typed in 120. What I want Excel to do is say that in order to meet the figure of 120, all tickets from the first batch need to be used and 20 tickets from the second batch need to be used. Ie ticket numbers 100 to 199 and 500 to 519 are used up.

The second part of the problem is that I'd also like to enter another number - for example 50 - and Excel would know to look at the available tickets from the second batch because the first batch is gone. I.e ticket numbers 520 to 569.

Is there a non-VBA way to do this?

TIA

I am sure there is. If I have understood correctly, then here is one way. I have ussed quite a few 'helper' columns so that the formulas don't become too long. Provided the formulas have been entered far enough down in these extra columns, the columns could be hidden if desired.

C3: =F3-D3
D3: =MIN(MAX(0,G3-$I$3),F3)
F3: =IF(COUNT(A3:B3)=2,B3-A3+1,"")
G3: =IF(F3="","",G2+F3)
I3: =SUM(H:H)

All formulas (except I3) copied down. The numbers you referred to as being entered in column C, I have entered in column H. However, all columns can be re-arranged as you see fit.

Was this anything like you wanted?

Mr Excel.xls
	A	B	C	D	E	F	G	H	I
1			Used from this batch	Remaining from this batch		Tickets in Batch	Total Tickets	Used	Total Used
2
3	100	199	100	0		100	100	80	140
4	500	599	40	60		100	200	10
5	800	899	0	100		100	300	30
6	1100	1199	0	100		100	400	20

This might be what you want. Keeps a running total of the balance at each entry, so you can add batches of tickets/requirements below as required.

A2 has your start batch number
B2 has your end batch number
C2 has formula =B2-A2+1
D2 has your number eg. 120 required
E2 has formula =SUM($C$2:C100)-SUM($D$1:D2)
(watch the $ positions - can copy/paste the formula from here)
can copy formulas down.

Peter and Brian. Thanks to you both for your help. Both work great so I'll tinker around with what I ultimately want to produce and use your formula.

I appreciate your help.
