Hi, Thanks for your answer. I'm trying to set the formulas for Line Items: Confirmed PO Delivery Confirm Purchase Order Receipt - Line Item 'PO Submitted' is a simple formula to the boolean line item 'Submit Purchase Order Request': IF Submit Purchase Order Request THEN 1 ELSE 0 Thats ok for me -Line Item 'Confirmed PO Delivery' This one is my struggle because I wanna check if Line Item 'PO Submitted' is > 0 and use the number of weeks to OFFSET it. Then my formula would be: IF PO Submitted > 0 THEN OFFSET(PO Submitted, Shipping Time Weeks, -1) ELSE 0 But this doens't look right and is not working as I want to. And -Confirm Purchase Order Receipt: IF Confirmed PO Delivery > 0 THEN OFFSET(Suggested Order Amount for the Month, Shipping Time Weeks, 0) ELSE 0 I have some doubts here because I want to see the value of line item 'Suggested Order Amount for the Month' from week 1 on line item 'Confirm Purchase Order Receipt' at week 3, right? And with those formulas I have the value from week 3 in week 1, it's the opposite Thanks again. Sara
