if statement modifies groups, what!?

Hi!

I have a bunch of primitives that can or not be in a group (i@group_frontDoor; i@group_upFrontDoor; i@group_backDoor; i@group_upBackDoor; ). I wanted to have an i@doorCheck to verify if the prim is in one of the door groups or not. The problem is the primitives groups gets modified by the IF statement. Why is that?!

i@doorCheck;
i@group_frontDoor; i@group_upFrontDoor; i@group_backDoor; i@group_upBackDoor;

if((@group_frontDoor = 1) || (@group_upFrontDoor = 1) || (@group_backDoor = 1) || (@group_upBackDoor = 1))
    {
    @doorCheck = 1;
    }

I'm pretty sure you need to use “==” for if statements like that. if(@group_frontdoor == 1)
A single “=” sets the value, even inside an if statement.
