How can I subtract two columns and check if the absolute value if less than certain value

Hi, I have attched the table, basically I wish to do the subtraction between column H and column B, Column I with Column C, to check if both absolute value are less than 1000, if so I wish to assign the corresponded value from column F to new a column.

e.g IF H2-any row from column B, I2-any row from column C, both less than 1000, find the row number in B/C, and assign the F value to a new column. If find multiple rows, do the average of corresponded F column value.

Note: Column H and I has more rows than Column B and C

I tried IF Vlookup but filed.

Many thanks for your help.

Welcome to the forum! Please take a moment to re-read forum rule #1 and then amend your thread title to something that better explains your problem. Changing your thread title is not optional, which means you must change it. Thanks!

• Use concise, accurate thread titles.
  
• Your post title should describe your problem, not your anticipated solution.
• Use terms appropriate to a Google search - poor thread titles, like Please Help, Urgent, Need Help, Formula Problem, Code Problem, and Need Advice tell us nothing.
• Responding to a request to change your thread title by doing so is mandatory.

To change a title go to your first post, click EDIT then Go Advanced and change your title.

No help to be offered, please, until the OP complies with this request.

Hi there, sorry about that. Just changed the title

Thanks. Will you now please attach your workbook (not a picture of it, with which we can do nothing) - nobody wants to have to recreate your data.

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.
