No it does'nt work
It's works with that
my dimension Joursemaine is made with this in my script
weekday(date) as JourSemaine // so it's giving lun. mar. mer. jeu. ven. as results
I tried to change my variable by setting
Label : Lundi
or value 'lun.' but it's not working ...
Have you checked the variable-value within a textbox if it returned what you expected. Further helpful might be this: Variables.
Btw. if you would use a listbox on the weekday it would be a lot easier.
