Formule colonne

[#1]

Bonjour à tous, J’essaye de faire un script JMP permettant de calculer des durées delta. Je dispose de 847 colonnes date début, 847 colonnes date de fin. Le script ci-dessous utilise une boucle for pour calculer la nouvelle valeur de chaque colonne « durée tâche x"(colonne déjà créé ultérieurement, x allant de 1 à 847). Merci pour votre aide.

An easier way might be to use the Date Difference() function. Example below:
