Variables are really useful.
First I used them to store formulas that have to be used several times.
It seems that they can be used for other reasons : (please feel free to correct me if I misunderstood !)
- If I DON'T put a equal sign in the variable formula, it can be used for my first aim
- If I DO put a equal sign in the variable formula, it can be used to do dynamic calculation that evaluate to only one value (if this variables in a table with one dimension, the variable provide the same value in all the lines)
What I don't understand is « when shoud i use quotes in the expressions that are using variables ?"
For example :
Why an expression like that works :
=$(Cout moyen par sortie) - '$(V_mediane)'
Where as the following do NOT works :
='$(Cout moyen par sortie)' - $(V_mediane)
=$(Cout moyen par sortie) - $(V_mediane)
KNOWING THAT :
$(Cout moyen par sortie) is defined by this formula -> Sum (MT_MASSE_SAL) / Sum (NB_SORTIES_MC)
$(V_mediane) is defined by this formula -> =median(
(sum(MT_VACS_MC) + sum(MT_MASSE_SAL))
Can you help ?
Thanks a lot for your help !
