lookup formula

Dallman Ross

I'm trying to do an HLOOKUP or something like it but am having
trouble. Here is a table from my sheet:

A B C D E F G
1 Symbol Last Price Stagger % $40 $30 $20 $10
====== ========== ========= === === === ===
2 ASTI $8.30 0.60
3 METH $16.26 4.92% 0.80
4 SOHU $30.08 1.20 0.90


Basically, I've put all the data in but want the formula for Column C.
For Column C, we want to take the last price from B and find the
next value above it in D1:G1, then look up the corresponding value in
D:G on the current row. Then we take what we found and divide it by
the last price.

I did it for B3 successfully. Here is the formula I used:

=HLOOKUP(10-MOD(ROUNDUP($B3,0),10)+ROUNDUP($B3,0),$D$1:$G3,3,FALSE)/$B3

I don't know if that formula's right or wrong, but the mathematical
result is right. That is, $16.26 from B2 is under $20, so we're
looking up values in Column F. The value we find is 80 cents in F3.
Now we divide that by $16.26 from B3, and we get 4.92%.

However, when I drag my formula to C2 or C4 I get error
messages. I'm not sure why. The ROUNDUP stuff seems to work, so far
as I can see. So the problem's got to be in my HLOOKUP formula.
(The dollar signs are just formatting; the numbers are numbers, also
in the header column.)

There are certainly going to be other approaches to solving this, as well.
I'm looking forward to seeing some!

Hmm. I seem to have gotten it to work by correcting one tiny thing
in my formula. I had
=HLOOKUP(10-MOD(ROUNDUP($B3,0),10)+ROUNDUP($B3,0),$D$1:$G3,3,FALSE)/$B3
..............................................................^

I changed that to:
=HLOOKUP(10-MOD(ROUNDUP($B3,0),10)+ROUNDUP($B3,0),$D$1:$G3,ROW(),FALSE)/$B3

That solves my immediate problem, but I still would be interested in
other (simpler?) approaches.

Still not right. If B3 is, e.g., $9.49, the lookup ends up being in the $20s
column; I want it to be in the $10s column (G below).

Hmm. Thinking out loud, here, but this seems to be better:

=HLOOKUP(10-MOD(B3,10)+B3,$E$1:$H3,ROW(),FALSE)/$B3

Try:

=OFFSET(G3, 0, -INT(B3/10))/B3

Drag the formula down.

As implied by your approach, the above assumes that the Last Price values
cannot exceed $40. If they can, then advise on how you want to treat this.

Forgot to meantion that you should format the Stagger % column as Percent
through Format > Cells > Number (if you haven't done so already).
