Values for individual items of a drop down list?

[JustinSchenck]

Hello,

I would like to assign a different value to each item of a drop down list, so that when I select a different item it would change the final value.

Right now I am using a basic "=F15*12" type formula, but I would like that numerical value to change with a drop down list I have in column D. 

I have different sized packaging with different weights. 

6x1 = 12

5x3 = 33

12x1 = 25

etc

Can anyone help solve this for me? Thank you so much in advance!

@JustinSchenck Perhaps the attached workbook will get you started. I have use a small lookup table (named "Sizes"), part of which populates the dropdown in column D and is used by VLOOKUP to find the weight. If you are on a recent Excel version, you might want to look into XLOOKUP as well.
