formulas to match row in a table from given values

[james]

I have a table where column A is the size of the material, e.g.
0.5",1",1.5"..., columb B is the thickness, e.g. 11,14,16, of the material,
column C is the weight of the material per size and thickness.
Each size (column A) has 3 or more thicknesses (column B). So I'm trying to
write a formula that will find the given (size and thickness) values on the
same row and return the weight from column C. I've tried
L-UP,VL-UP,HL-UP,MATCH,INDEX.
MY HEAD IS SWIMMING.
Might anyone have a suggestion. advil aint workin no more. hope this isn't TMI
Thanks for any response.

A multi-criteria index n match (array-entered) should work here
Assuming paired inputs made in E2:F2 down,
eg in E2: 0.5 (size), in F2: 14 (thickness)
put in G2, press CTRL+SHIFT+ENTER to confirm the formula (ie array-enter):
=INDEX($C$2:$C$100,MATCH(1,($A$2:$A$100=E2)*($B$2:$B$100=F2),0))
Copy G2 down to return the corresponding weights. Adapt the ranges to suit.

Max~ just one ?. When I enter the thickness ie 16 it changes to 1.6E+01.
This is not a complaint only a ?. I've studied the formula and have learned
alot
and realize I need to learn more on array entered formulas which I will as
time goes by. As for now I WILL SHOUT IT WITH MY LOUDEST FONT THANK YOU X
A GUZILLION. FOR YOUR HELP . I only hope that one day I can be of some help
to another user as the group in this community has been for me. Even those
who pose ?'s have helped THANKS TO ALL.
