I'm making a calculator that requires the input of two out of seven variables. I figure there are about 42 possible combinations. I started by just using if , elseif etc. but quickly had such a mess I lost track of where I was. I'm thinking that maybe selsct case would be the way to go, but I've never used that before, could someone show me or have a better method. I'm using VB4 pro 16bit, my input variables are text6 - 12.
