The type 'ModifyingAttribute' does not contain a constructor that takes '2' arguments.

Heres a copy of my code in which i am receiving the errors.

 using UnityEngine;
 using System.Collections;

Apparently its that line. Line 84 :)

Here's a copy of my other cSharp file that contains the modifiying attribute.

 using System.Collections.Generic;
     
 public class ModifiedStat : BaseStat {
     private List<ModifyingAttribute> _mods;        //A list of Attributes that modify this stat
     private int _modValue;                        //The amount added to the baseValue from the modifers.
     
     public ModifiedStat() {
         _mods = new List<ModifyingAttribute>();
         _modValue = 0;
 }
     
     public void AddModifier( ModifyingAttribute mod) {
     _mods.Add(mod);        
 }
     
     private void CalculateModValue() {
         _modValue = 0;
         
         if(_mods.Count > 0)
             foreach(ModifyingAttribute att in _mods)
             _modValue += (int)(att.attribute.AdjustedBaseValue * att.ratio);
     }
             
             public new int AdjustedBaseValue {
             get{ return BaseValue + BuffValue  + _modValue; }
     }
         
         public void Update() {
             CalculateModValue();
     }
 }
         
         
     
 public struct ModifyingAttribute {
     public Attribute attribute;
     public float ratio;
