why wont this line of code compile?

Z == X <> 0? Y/X*100 : 0;

this wont compile...


it says, invalid expression
on the 0 it says expected ;


it suppose to set Z to be Y/X *100 if X <> 0, if false then set Z to be 0.

help help help,

Hello James377,

== is for comparing equality.
= is for assigning values.
!= not equal to.

You should use:
z = x != 0 ? y / x * 100: 0;

This tutorial walks you through setting up this type of statement if you're looking for more examples.

for another line I am getting an error message saying doesnt exist in current context,

but i have declared this variable as a public double? it should exist everywhere shouldnt it?

No, you will want to declare variables as private and accessed within the script. Public variable declarations are only used when:

• They need to be used as user defined inputs.
• You're attempting to access values from another script using this approach.
