Joel,
You are looking for something like this logically:
if(!($var(is_a_present) == $null && $var(is_b_present))){
# a and b exist
} else if(!($var(is_a_present) == $null){
# a exists
} else if(!($var(is_b_present) == $null)){
# b exists
} else {
# failover
}
Sincerely,
Brandon Armstead

I was wondering how many levels deep in conditional
_if_ _else_
statements can go. I need to create a statement that has 4 possible
outcomes and need to know if this is possible.
I have two variables
I want one thing to happen if only the first variable is present
Another if only the second variable is present
Yet another if they are both present
And a fail over if None of the variables are present
I do see that is can be done with 3 conditions using _if_ _if else_
_else_
how can I accomplish 4 conditional statements?
Thank you in advance
Joel
