Matcad Pro if statement

[YSINC]

I am a new user and I am having trouble with an if statement:

determine:
if, v1<=v2 then, fb1
if, v2<v1<=V3 then, fb2
if, v1>v3 then, fb3

write:
the result for fbn=xxxxx

if(v1<=v2,fb1,if(v1>v3,fb3,fb2))

Thank you,
I figured it out. The help file in my software states do not type the "if" statement use the programing toolbar button. I did this and the "if" was preceeded by a placeholder, which was irremovable causing an error. Anyway, I finally decided to type the "if" and it worked fine. Thank you for the reply.

The programming toolbar "if" is a program control statement, whereas "if(,,) is a built-in function.
