Hi again,

I write you again, perhaps this time somebody can help= me solve the problem.

Suppose I have a list like this

* = TODO v=C3=AAtements [0/0]=C2=A0=C2=A0=C2=A0 =C2=A0=C2=A0=C2=A0 =C2=A0=C2=A0= =C2=A0 =C2=A0=C2=A0=C2=A0 =C2=A0=C2=A0=C2=A0 =C2=A0=C2=A0=C2=A0 =C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 :total:
=C2=A0 :PROPERTIES:
=C2=A0 :total:=C2=A0=C2=A0=C2=A0=C2=A0 0
=C2=A0 :END:

=C2=A0 - po= ur week end
=C2=A0=C2=A0 - [ ] X =C2=A0=C2=A0 30
=C2=A0=C2=A0 - [X] Y= =C2=A0=C2=A0=C2=A0 80
=C2=A0=C2=A0 - [ ] Z=C2=A0=C2=A0=C2=A0 100
=C2= =A0=C2=A0 - [ ] W =C2=A0 20
=C2=A0 - pour les loisirs
=C2=A0=C2=A0 - = [X] X =C2=A0 30
=C2=A0=C2=A0 - [ ] Y=C2=A0 80
=C2=A0=C2=A0 - [ ] Z = =C2=A0 10
=C2=A0 - pour la maison:
=C2=A0=C2=A0 - [ ] pantoufle 25

I want to add all values of the fiel= ds that are crossed and keep the sum into the value of the property 'to= tal'. Is it possible to do it using org mode ? I looked over many docum= ents, but not found.

Other problem, suppose I have this table inside the same file.

I wish to sum the v= alue of the variable \$montant with the value of the property 'total'= ; from the other part (from the list), and use the result in other computat= ions.

Are these things possible using org mode ?

I looked today over s= ome examples of babel language, but I did not find what I need.

Thanks in advance for any help.

Hi,

I have been using org mode for a few days and I am impressed.
I have followed a few tutorials and videos, however I want to solve a = problem and I did not find how can I do it.

I have 2 tables , and ev= ery such table has a variable \$sum, that is the sum of a column. Because I = am lisp engineer, I used the formula '(+ @I..@II);N to compute it, I pr= efer lisp to calc.

My problems are

1: to export the value of the \$sum from one tab= le, and make global computations using it
2: to compute the value of som= e property in function of such variables, defined inside tables.

Afterwards, can I compute the value of a property in function of the value = of other properties ?

Probably my question is stupid, I do not know,= because I did not understand yet the principles of properties of org mode.=
