Accessing components/variables?

Hello. I am trying to use GetComponent to access public variables that are in another script, but I keep getting errors(such as "An instance of type 'UnityEngine.Component' is required to access non static member 'GetComponent'.").

I want to make a pokemon style turn based RPG. I am going to have all of the available moves that the monster can do be functions and store those functions a single Moves_Database script. Then, when a monster goes to execute a move, that move's function would be called, but it would then be modified by the stat values inside that particular monsters script.

he way he battle system works, is first the script scans the scene for all objects with the enemy tag (which all have the "Enemy" script attached), then, targets a specific enemy, then it it accesses that enemy's specific script (the enemy's stats are public variables), and then, for the attack, it enacts some sort of modifier on those stats (subtracting HP, decreasing agility, etc.).

Here is the the one that invokes the other script's function(its called B_Controlled)

public var Monster_List :GameObject[]; public var Monster_SLCT =5; public var Attacks_SLCT : String;

function P1 (){Monster_List=GameObject.FindGameObjectsWithTag ("Enemy");} function P2 (){Monster_SLCT = 10;}
function P3 (){Attacks_SLCT = "THUNDER";} function P4 (){Invoke(A_Moves.Attacks_SLCT);}

And here is the moves database (A_Moves)

static function THUNDER (){ //This is the part of the function that finds the enemy that the B_controlled script found. GetComponent("B_Controlled").Monster_List[GetComponent("B_Controlled").Monster_SLCT]

//and this part affects the stats of the Enemy script .GetComponent("Enemy").HP-=1; }
