Hi Ian. To preserve your original Planned Amount (eg "OPA") consider adding a custom data form to your expenses with a calculated currency parameter with a formula such as this: IF(ISBLANK(OPA),Planned Amount,OPA) which is a technique (ok, a trick) that basically "captures" the Planned Amount into the OPA parameter the first time the Expense is saved, and then (because it is not blank after that) "preserves it" even if the Planned Amount changes. You can then report Planned Amount vs OPA, and filter where they are different, do a % difference calc, etc. -- excellent for the executive audience you have in mind. If you want to Get Fancy, you could make the IF statement smarter to allow a reset (mistakes happen, plans change, etc.) Regards, Doug
