Expression editor...

Can someone explain the subtleties of how expressions are handled in the expression editor? I must be missing something obvious here. In the attached image want to make a simple function with three variables - all doubles. I call them pc, max, min. The expression is very simple: (pc*(max-min))+min I tried either with the F(x)3 component or the F(x)n with 3 inputs, the expression editor in F(x)n gives me the warning "invalid, expected ( instead of -"

I then tried naming the variables x,y,z and it seems to work with either component... so, what am I not understanding here? Thanks for any light you can shed... --Mitch

Hello Mitch,
Max and Min are reserved keywords in the expression editors. They are functions you can use, thus, their names are not a good idea to use elsewhere. I often use MX or MN to denote max and min. Naming any input or slider 'Max' or 'Min' is not a good idea.

Hey Luis,
OK, that explains it, thanks! - I really thought I was going nuts! I will keep an eye out for this kind of stuff in the future...
Ciao, --Mitch

you can check out in the expression editor the function list...avoid these words unless you want to use them in an expression...
