New to MVC and getting classes are not declared even if their files have been loaded

Im brand new to MVC and this is my first app. Im getting


The following classes are not declared even if their files have been loaded: 'iPal.store.prodStore', 'iPal.store.custStore'. Please check the source code of their corresponding files for possible typos: '/iPal/store/prodStore.js', '...<omitted>...js


I dont know what it means by "declared". I have two store(s) and both are getting the error. This config is AS/400 centric so it may not resemble a windows or linux config. I was the only way I could get it to find the files. I built my stores from the SenchTouch in Action Examples. Any clues what Im doing wrong.

Code:

 Ext.Loader.setConfig({          
      enabled : true               
   });                             
                                   
  Ext.Loader.setPath({             
       iPal : "/iPal",             
  });                              
                                                                       
 Ext.application({                                                     
   name: "iPal",                                                       
   appFolder: "/iPal",                                                 
     models: ["iPal.model.prodModel", "iPal.model.custModel"],

     controllers: ["iPal.controller.Main"],                            
     views : ["iPal.view.login", "iPal.view.prodList"] ,
