Function not excuting dispite being called

Sorry to pester you all again, but I have another scripting problem. For context, I'm working on a turn-based RPG battle system, I'm having fun programming it but something really weird is happening (here's my code for reference).

 ///<summary>The folowing code outlines the functions and routines that make up the battle system,
 ///to begin with the program fetches the stats of the enemy and the player (HP, MP, Strength
 ///and resislience) and makes them the value of their respective varibles. 
 ///The main loop can then begin, the progam will first check the HP values of both parties
 ///player first, to determine wether their has been a win or a loss.
 /// A "coin" is then tossed to decide turn order, if the coin "lands" on "heads" 
 /// the player can take their action first on that turn. </summary>
 
 //Libaries are called here.

If you've managed to follow my comments so far across this monstrosity you'd notice a function called "EAttack()", when called this is supposed to make the enemy attack the player. But for some bizarre reason when unity gets to the line of code denoting to execute that function it completely skips over it like it didn't exist. Did I do something wrong?
