You must assign a value to the choice you have selected.  You can only
assign integer values between -100 and 100.  The value -100 is equivalent to
"absolutely no" and the value 100 is equivalent to "absolutely yes".  The
values between represent degrees of certainty between these extremes.
The value will be displayed followed by "/100".

The values DO NOT permanently set the value for the choice. The
final value for a choice will be the average of the various values given
to that choice in the rules that were found to apply.  The
average value will be the first value displayed in the sorted list.

You will also have the option of having the final value calculated as a
dependent probability of the various values (treated as probability
percentages).  This will give a value calculated by multiplying together
each of the values (divided by 100) for a choice from the rules where
it was used.

Alternatively the final value can be calculated as an independent
probability with the final value calculated as:
    100 * (1 - (the product of (1 - (the values assigned / 100))))
