Mongoose TypeError when creating a schema that used Number

I've got a schema that uses numbers as follows.

var mongoose = require('mongoose')
    , Schema = mongoose.Schema
    , ObjectId = Schema.Types.ObjectId
    , Mixed = Schema.Types.Mixed
    , Number = Schema.Types.Number
    , Date = Schema.Types.Date

var ItemSchema = new Schema({
    quantity:{type:Number, required:true, min:1},
    category:{type:String, required:true, enum:categoryList},
    description:{type:String, required:true},
    cost:{type:Number, required:true, min:0, default:0},
    appraisedValue:{type:Number, min:0, default:0},
    appraisedOn:Date,
    purchasedOn:Date,
    purchasedFrom:String,
    brand:String,
    dynamicFieldList:[DynamicFieldSchema]
})
exports.ItemSchema = ItemSchema
exports.Item = mongoose.model('Item', ItemSchema)

But when I attempt to run my application, I receieve a TypeError: Undefined type at 'quantity'. This also occurs at 'cost', if the quantity value is commented out.

The stack trace is:

C:\Users\a\Documents\Git\has-inventory.js\node_modules\mongoose\lib\schema.js:325
throw new TypeError('Undefined type at `' + path +

TypeError: Undefined type at `quantity`
  Did you try nesting Schemas? You can only nest using refs or arrays.

Remove these two lines:

, Number = Schema.Types.Number
, Date = Schema.Types.Date

The built-in JavaScript Number and Date types should be used in the schema defintion instead.
