hi, Rachel !

not sure i'm following you correctly (but) you might want to give a try...

=--if(d7<"na",and(d7=2,f7<100))

hth,
hector.

__ OP __
I'm completely self taught so hope this is possible
I've tried a number of formula but the nearest is
=IF(($D$7<2)*($F$7100)*($D$7="NA"),0,1)
what i need to do is assign a value of 1 or 0 when adding different arguments
I need a result of 0 if D1 is under 2.00 F1 is over 100 or the result in the D coloum reads NA
can't change NA to read something else as its imported from another source.
I also need a result of 1 if D1 is 2.00 or over, if F1 is under 100
everyway i try to do this counts NA as being larger than 2.00
Any help gratefully received, thanks

Hi Hector, Thanks for your help, thought that had almost worked but it didn't.

Animal, Error Rate, Count

Dogs, 0.20, 38, *
Cats, 7.00, 120, *
Birds, NA, 0, *
Frogs, NA, 150,
Hamster, 1, 500,
Basically I need to Find total of error rates over 2.00 and counts under 100 but i need NA to equal 0 and as its imported from elsewhere text needs to be NA. I have put a star at coloums that should count as 1 as if a row fits errors over 2.00 and count under 100, it should still count as 1 and not 2

There are many ways to write this that should all work. Here's one:
=IF(D1="NA",0,IF(AND(D1=2,F1<100),1,0))

But, in your example you say those starred should all be a 1. But you
said 1 should be returned if the rate is over 2.00 AND count is under
100. (did you mean OR?)And you said anything with an NA should return
0. By my reading, all of your examples should return 0.

Also, in your 2nd post you suddenly mentioned returning a 2. Is that a
typo?

So, what is wrong in your posts? Need to get that fixed first.
