Hi Joaquin,

For the question that you want to give a value of 0 or 10 depending on
another question's answer, in the form designer's properties tab, put this
expression in the question's calculate property:  /form/obs/fieldname/value
== 'no' ? 0 : 10

Replace "fieldname" with the actual one which you can see in the binding
property.

If we keep uppermost in our minds the unkind and unjust acts of others, we
shall find it impossible to love them as Christ has loved us; but if our
thoughts dwell upon the wondrous love and pity of Christ for us, the same
spirit will flow out to others.
