I have a worksheet (sheet 1) which looks like this:
item name | quantity | sold | damaged stock
keyring | 100 | 20 | 5
ball | 100 | 55 | 1
and another worksheet (sheet 2), which is for damaged stock recording, and looks like this:
damaged date | item name | quantity damaged | type of damage |
01-01-2012 | keyring | 2 | water |
02-01-2012 | ball | 1 | fire |
03-01-2012 | keyring | 3 | robot attack |
Now what I want to do is calculate the total number of individual damaged items in sheet 2 and add them to sheet 1 automatically (ie for keyrings, 2+3 in sheet 2 = the 5 in sheet 1)
Really appreciate the help! thanks
