Sorry everyone, I just found out that the issue was because my computer was
in French and not in Englist, so the formulas need to be translate in French.

Also since I use a 6 letter Julian date, I change something in the formulas.
Here is what I used :

DATE(SI(0+(GAUCHE(F2,2))<30,2000,1900)+STXT(F3,2,2 ),1,DROITE(F2,3))

Tks

day 64 of 2007.
