Hi all, almost finished my mail franking page which is very exciting! One slight hitch though! I’m trying to add a savings stat so the company can see how much we save each much by using franking instead of stamps, I have attached a photo of the current way the RG looks with it’s stats box

I’m trying to make the circled “Savings” box actually work out the savings out of all the mail entries however struggling to work out how to ask the bubble box how to work the savings out. I drafted this quickly on excel and it worked so was wondering if anyone might be able to translate the excel version into a way of using it in bubble?

Many thanks!,

James
