Formula To ADD values from different columns

Hi I am new to excel and need help in adding values in my sheet.

the contents are as follows:


NAME -------- TAG ---- CODE ---- QTY ---- BIN#
AIRWEAR ---- A411 ---- 0ES3 ---- 1 ---- 1
ARISTAR ---- 6344 ----017 ---- 1 ---- 1
AIRWEAR ---- A405 ---- 0DJ3 ---- 1 ---- 1
AIRWEAR ---- A402 ---- 0E98 ---- 1 ---- 2
AIRWEAR ---- A416 ---- 0TM7 ---- 1 ---- 2
AIRWEAR ---- A405 ---- 0DJ3 ---- 1 ---- 2
AIRWEAR ---- A411 ---- 0ES3 ---- 1 ---- 2


The above are some values in my sheet, now I want to add the qty of the items based on the bin number, so basically i need to know how many items are there in each bin, is there a formula i can use to find out, i have around 2300 rows of items with approx 300-400 bins and i dont want to manually count each item and bin. Sorry if my explanation is confusing. Thank you for your help.

regards,
Laurier
