[Beginner's Question] How do I compare variables and divert from the highest/lowest?

Please forgive me if this is obvious but I am a novice to programming and I am not smart enough to figure out an answer to this from github thus far.

In my game I have various "personality" stats that I am tracking as integer variables. For example:

VAR Diplomacy = 0
VAR Investigation = 0
VAR Deception = 0
VAR Intimidation = 0

Different choices boost the values of these variables. For example:

*[Talk it out]
~ Diplomacy = Diplomacy +1
*[Dig through his trash]
~ Investigation = Investigation +1

Now my question: At different points, I would like the character diverted into particular knots/stitches based on whichever of these variables is higher. So for example, if after making choices the character has these stats:

VAR Diplomacy = 2
VAR Investigation = 1
VAR Deception = 0
VAR Intimidation = 4

Than in this case, the player should be diverted to the "Intimidation" path.

The problem is, this doesn't seem to work the way I set it up. If I use && for this logic, I cannot move past this checker.
{
-Diplomacy > Investigation && Deception && Intimidation:-> PathA
-Investigation > Diplomacy && Deception && Intimidation:-> PathB
-Deception > Diplomacy && Investigation && Intimidation:-> PathC
-Intimidation > Investigation && Deception && Diplomacy:-> PathD
}
I thought this would work but I get a "ran out of content" error.
If I use ||, than Diplomacy will be selected since it is higher than Investigation or Deception, which I don't want.

I know for sure that I have successfully implemented the variables and modifiers as I have tested for them. What I want is for all these four variables to be compared and the highest one selected.

Thanks so much for any help you are willing to offer!
