Hi :)
Don't self referencing equations usually tend towards chaos and have fractal dimensions? It's a
bit beyond the scope of a spreadsheet! Is there a way of limiting the number of iterations or does
Calc just protect it self (and the cpu) from calculations running away towards chaos?
Regards from
Tom :)

As others have stated, "T2=T2+..." will fail, because it references its own result.
For this example, you might put this in T2:
=IF(OR(F2=0,L2<3),0,F2+L2)
Translation:
1. If F2=0, then T2=0
2. If L2 is less than 3, then T2=0
3. If F2 is greater than 0 and L2 is greater than 2, then T2=(F2+L2)
But (also as others have said) you do need to plot out all the scenarios and what their answers
should be. What my suggestion above assumes is:
If F=0 then T=0 regardless of what L is
If L<3 then T=0 regardless of what F is
If F>0 and L>2, then T=F+L

Thanks to all for the previous help,
Also, sorry if you have addressed this already, Brian. But, I know only basic functions within
the spreadsheet and will request a more explanatory example.
The file was delivered in xlsx format. I would like to maintain the format (using LibreOffice!),
but I may have to look to other software.
Here is an example of my first two rows of data, cells F2&3 through S2&3, with F1-S1 containing
variable names
*F* *G* *H* *I* *J* *K* *L* *M* *N* *O* *P* *Q* *R* *S*
0 1 0 1 0 0 1 0 0 0 0 0 0 0
1 0 1 1 0 0 1 0 0 0 1 0 0 0
Using a simple example with only two cells (F2&L2), I want T2 to equal a 'score' based on a
weighted index, like this:
IF F2=0 then T2=0; else T2=T2+1;
(Where F2 can only take on a value of 0 or 1)
AND
IF L2=0 OR L2=1 OR L2=2 then T2=T2+0; else T2=T2+3
(Where L2 can take on a value of 0,1,2,or 3)
So that:
T2 = 0 (if F2=0 and L2=0,1,or 2)
OR
T2 = 4 (if F2=1 and L2=3)
I haven't been able to create the proper syntax for this simple two cell scoring.
How can I not only score an individual cell but also link it with another cell in the same row?
A simple demonstration will be adequate so that I can create my specific and more complicated
function.
I hope I have stated my needs in a clearer fashion this time around, and thanks to everyone for
the previous help.
Regards,

Hello all,
I have a simple question for which I cannot find the answer.
I have a LibreCalc spreadsheet containing binomial data for which I
would like to create a final summed "score" (in Column T) based upon a
manually specified score index.
Columns F, G, H, J, K, M, N, O, P, O, and R contain pure binomial
information (0 or 1)
Columns I, L, and S contain multiple numbered responses:
I = 0,1,3
L = 0,1,2,3
S = 0,1,2
I want to create a final score (Column T) based upon numerical responses
(in Columns F-S)
All this makes me think of binary data, hence to have columns F..R (except I, L & S) set to hold
either 0 or a power of 2.
F would hold 0 or 1
G 0 or 2
H 0 or 4
J 0 or 8
and so forth.
Then, adding any group of columns would then give a unique meaningful value:
-- if you add F+G+H and get 3, you know that only F and G are set
-- if you AND F+G+H with, say, 2, you may check if G (value 2) is set : if G AND 2 = 2 then G is
set (in Calc use the BITAND function)
As I don't know exactly what you're looking to achieve, perhaps my idea is useless.
Anyway, just my two euro-cents,
