Would be great if some one could help. I have an inventory list which
would have over a 100 different products on it. These products are
distributed to different departments in my business. Sheet 1 I type in
the department name then part number and how many items, then vlookup
brings up the info. But I can not work out how to subtract the amount I
just entered from the inventory list which is in sheet 2. The same
product can go to many departments. Have tried this but will only work
on one line. =IF(Sheet1!A1:A100=100,(Sheet2!C1-(Sheet1!D1:D100)))
"100" being the part number. Thanks in advance.
