Re: [libreoffice-users] Help with Scoring Bi-nominal Responses

Hi Paul,

Just another question here: where does the data come from? Directly 
entered by the user? Extracted from elsewhere? Exported from some software?
IOW, do you have the hand on the values (the zeroes and the ones in the 
source columns, the result lists in the result columns)?

As stated in someone else's message, the above formula for T2 (T2=T2+1) 
is self-referencing which will result in an infinite loop. You'll have 
to compute the result in another column, I guess.

I'd start with a sheet of paper, drawing a table of possible values: for 
each input column and for each value, write down the output column 
values. From such a sketch, it would be much easier for you to figure 
things out.
I'm sure your calculations might be simple. IMO, the first thing to do 
is re-think the whole thing as large "table" and analyse the output 
values ranges. Then deducting the formulas is a no-brainer ;)

Depending on the needs, the IF() and SUMIF() functions might be of help. 
Sorry to be vague here as I don't quite understand the question :)
