I'm trying to creat a formula that states. If tank 1 maximum capacity is less than 500,000 and the difference in inventory is greater than the absolute value of 10% or 20,000 or if the tanks maximum capacity is between 500,000 and 1,000,000 and the difference in inventory is greater than the absoulte value of 20% or 100,000 or if the maximum tank capacity is greater than 1,000,000 or the difference in inventory is greater than the absolute value of 30% or 300,000 then Y OR N.I hope my question is clear. I'm wondering if I need to simplfy the scenario. I figured out the absolute value portion of the formula but I'm not really sure how to combine that with the tank maximum capcity piece.=IF(OR(ABS(T14)>10%,S14>20000),"Y","N")Well I'd appreciate any help that anyone could offer. This is my first post on the forum so let me know if I need to add more details. Thanks.
