Conditional Problem

Hi guys, I have an interesting problem with the conditionals.
In the please where the message is when you submit I have 5 nested conditionals. I want to have different output message when at least one question is answered “NO”.
Here is an example with YES and its ok 🙂

[if 15 equals=”Yes”]
[if 13 equals=”Yes”]
[if 91 equals=”Yes”]
[if 95 equals=”Yes”]
[if 105 equals=”Yes”]
This is great because conditional works.
[/if 105]
[/if 95]
[/if 91]
[/if 13]
[/if 15]

But if I have any of these NO then I want to output different message.
From what I see there is no ELSE function here so not sure what to do.
