Subtracting Column Values determined by another cell value

[geNebee]

Hi there,

I'm trying to create an inventory table on our stock.

Everyday there will be inventory produced and delivered out.

eg.

A1 to A10 is incoming stock
B1 to B10 is outgoing stock
C1 to C10 is Stock remaining.

(A1-B1=C1, C2=C1+A2-B2 etc....)

The problem is that my inventory has cure time before sending out. Let's say, I have a cell which I can key in like '5' days cure time, the Stock remaining at C10 will minus away those produced in the last 5 days (incoming) meaning from B10,B9,B8,B7,B6 and the results at Row 10 which is where the stock remaining is will change accordingly to what I keyed in which in this example is '5'.

How do I link formulas up?

Welcome to the forum!

Will you please attach a sample Excel workbook?

1. Make sure that your sample data are REPRESENTATIVE of your real data. The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

2. Make sure that your desired results are also shown (mock up the results manually).

3. Make sure that all confidential data is removed or replaced with dummy data first (e.g. names, addresses, E-mails, etc.).

4. Try to avoid using merged cells as they cause lots of problems.

Unfortunately the attachment icon doesn't work at the moment, so to attach an Excel file you have to do the following: just before posting, scroll down to Go Advanced and then scroll down to Manage Attachments. Now follow the instructions at the top of that screen.

Please pay particular attention to point 2 (above): without an idea of your intended outcomes, it is often very difficult to offer appropriate advice.

Noted. First post. Sorry.

I've attached a basic document. On the first Tab, it stated 7-3 days cure time. I want to remove it to save rows and a formula which I can key in to see how much stock I have.

You have missed the most vital part:

2. Make sure that your desired results are also shown (mock up the results manually).

We really don't need to see the complete project - just a sample sheet showing what you are trying to achieve.

That's much clearer - thanks. I have run out of time for now, but someone will take a look soon.

The minus part is H7
=SUM(INDEX($C4:H4,MAX(1,COLUMNS($C4:H4)-$L$5+1)):H4)

Not sure how you get 163 G5+G6 = 23+139 = 162
