this may be easy, but it has me stumped. I need to create a spreadsheet that
will provide totals based on criteria set in a separate list.

TICKER SYMBOL MARKET VALUE SECURITY CLASSIFICATION CODE
DD 7934.4 401
GE 26974.4 416
DSX 15425 418
VZ 9506.79 429
WIN 5593.5 429
CMCSA 2601 435

I need to total the market value based on a list kept in a separate sheet

LG VAL LG BLEND LG GRTH MID VAL
400 500 600 800
402 501 630 810
418 502 631 811
484 505 635 812


I would like to build it this way because the security class codes (criteria
for summing) will change over time. I want to be able to update the list
without having to update all of the formulas.

is this possible?
