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
