Value will not return from ArrayList, C#

I currently have an file parser with a Get method:

 public string Get(string key){
         Debug.Log("key="+key);
         for(int i = 0; i < keys.Count; i++){
             Debug.Log(keys[i]+":"+vals[i]);
             if(keys[i] == key){
                 return vals[i].ToString();
             }
         }
         return "";
     }

Being called from another script:

 public enum GraphicSettingType{
     resolutionW,
     resolutionH,
     windowed,
     quality
 
 }
 
 public class GraphicsSettings {
 
     iniParser parser = new iniParser();
 
     public void Create(){
         parser.Set(GraphicSettingType.resolutionH.ToString(),Screen.currentResolution.height.ToString());
         parser.Set(GraphicSettingType.resolutionW.ToString(),Screen.currentResolution.width.ToString());
         parser.Set(GraphicSettingType.windowed.ToString(),Screen.fullScreen.ToString());
 
         parser.Set(GraphicSettingType.quality.ToString(),"1");
 
         parser.save(IniFiles.GRAPHICS);
     }
 
     public void load(){
         parser.load(IniFiles.GRAPHICS);
 
         Debug.Log("returned: "+parser.Get("resolutionW"));
 
         //int sW = 0; //int.Parse(parser.Get(GraphicSettingType.resolutionW.ToString()));
         //int sH = int.Parse(parser.Get(GraphicSettingType.resolutionH.ToString()));
         //bool iW = bool.Parse(parser.Get(GraphicSettingType.windowed.ToString()));
 
         //Debug.Log(sW+":"+sH+":"+iW);
         //Screen.SetResolution(sW,sH,iW);
     }

But it will not return a value, even though the name should be match on the loop.
