Cannot read property 'schema' of undefined

Not sure where I’m going wrong here, please kindly assist:

Client side HTML:

> <template name="NewPerson">
>     <div class="new-person-container">
> 	 {{> quickForm collection=Person id="insertPersonForm" type="insert" class="new-person-form"}}
> 	</div>
> </template>

Client side JS:

if (Meteor.isClient) {
 Template.NewPerson.helpers({
  PersonSchema: function(){
    return schema.PersonSchema;
  }
});
}

Schema:

Person = new Mongo.Collection('person');

Person.allow({
	insert: function(userID, doc){
		return !!userID;
	}
});

const PersonSchema = new SimpleSchema({
	FirstName: {
		type: String,
		label: "First Name"
	},
	LastName: {
		type: String,
		label: "Last Name"	
	},
	IdentityNumber: {
		type: Number,
		label: "Identity Number"
	},
	Address: {
		type: String,
		label: "Address"
	},
	PhoneNumber: {
		type: Number,
		label: "Phone Number"
	},
	User: {
		type: String,
		label: "User",
		 autoValue: function(){
         return this.userId;
      },
      autoform: {
            type: "hidden", 
            label: false,
		 },
		
		},
	
	//createdAt: {
	//	type: Date,
	//	label: "Created At",
	//	autoValue: function(){
			
	//	}
	//	autoForm: {
	//		type: "hidden"
	//},
	
});

Person.attachSchema(PersonSchema);
