I was looking for an excel spreadsheet calculator that worked like e juice me up ... Wanted simple and wanted several flavor options in the recipe mix... Finally found an excell download on a merchant site... Wasn't quite what I wanted but provided a good start and pointed me in the right direction for the math/cell formula issues... Anyhow... Attached is what I came up with... I wanted a lot of options for flavor add ins... I generally don't get all the way to 10, but hey, wanted the option... Usually get past 4 or 5 flavors and end up with Gym Socks but, once in a while you get lucky... Thought I'd share... Nothing's locked or protected so have at it if you want to modify... Happy Thanksgiving!
