Hello, I am having an issue with IF THEN ELSE forumla syntax. I have the following fuctioning forumla, in the context of converting weeks to months. IF Start Difference <= -23 AND Start Difference >= -28 AND End Difference >= 7 THEN ITEM(Week) ELSE BLANK I am trying to add a condition that says if the week start date is a hard date, then also return the ITEM(Week) date. Neither of the forumlas below are working. Does anyone have a suggestion on how I should be adding the Period Start nested formula? Thanks for any help!! IF Period Start = 1/1/2017 THEN "Week 5" ELSE IF Start Difference <= -23 AND Start Difference >= -28 AND End Difference >= 7 THEN ITEM(Week) ELSE BLANK IF Period Start = 1/1/2017 THEN ITEM(Week) ELSE IF Start Difference <= -23 AND Start Difference >= -28 AND End Difference >= 7 THEN ITEM(Week) ELSE BLANK
