Let me first say, thank you both for all your assistance, Biff and Dave.
Unfortunately, the below formula DOES NOT do exactly what I want. I wish it
did.
F6+Sheet2!F8,"")
........the formula I suggested DOES EXACTLY WHAT YOU ASKED FOR!
Believe it or not, Dave, yes I did mean to use different sheets. But if this
is a bad idea, then I will put the information on one sheet. I know enough
about Excel to be dangerous, but not enough to be proficient. So ... if you
suggest one data sheet, then I will try it.
THE REASON I WANTED different sheets is because the data is sooooo
cumbersome on just one sheet. I was trying to make it "user friendly" for
myself.
I tried your formulas and reworked them to what I think for my multiple
sheets:
=SUM(IF(Calculator!$B$5:$B$52>0,'Daily Consumption'!$B$4:$B$51,0))
It's already cumbersome keeping track of initial intent. I am thinking an
array that fills in multiple data is actually what I want ...
My purpose ... keep track of daily vitamin and nutrition intake . So, I have
created one sheet with Daily Recommended Vitamins (I call Vitamin Check) from
Biotin to Zinc. I'd like to ultimately compare this information with my
actual consumption.
I created another sheet that actually has the vitamin content of Centrum,
and other vitamin supplements. I will add to this with such things as
chicken, hotdogs, ham, etc ... you get the picture: CUMBERSOME.
Anyway, I created a third sheet to tally underneath "each day of the week"
my vitamin intake of all things consumed that day. So, if all things worked
accordingly, when I checked off Centrum in the sheet I call Daily
Consumption, then my formula (or array) will look at my Calculator under the
Centrum column and put all that information into a fourth sheet (right now I
simply call Sheet3). It is meant to be a running tally for the day, each time
I check an item ... chicken, it will add the total protein value (or other
value) to the appropriate column in Sheet3.
I hope I am explaining myself well enough to give you a clear picture of my
intent. Like I said, I know only enough to be dangerous. But am having fun
strengthening my knowledge.
I am in the process of reading your suggested articles, Dave, and await to
hear any opinions regarding how best to achieve my goals.
Thanks again, Biff and Dave.
