I've read through several posts on the Connect Components with Events challenge, and I'm still not seeing what's wrong with my campingListController.  I'm getting the Challenge Not yet complete message. "The campingList JavaScript controller isn't setting the 'item' as a parameter or saving the record correctly"

Can anybody tell me where I'm wrong?

campingList - Controller

({

    //
    //      Load Camping Items at startup
    //
    doInit: function(component, event, helper) {
        // Create the action
        var action = component.get("c.getItems");

        // Add callback behavior for when response is received
        action.setCallback(this, function(response) {
            var state = response.getState();
            if(component.isValid() && state === "SUCCESS") {
                component.set("v.items", response.getReturnValue());
            } else {
                console.log("Failed with state: " + state);
            }
        });

        // Send action to be executed
        $A.enqueueAction(action);
    },

    handleAddItem: function(component, event, helper) {
    	var item = event.getParam("item");
      	var action = component.get("c.saveItem");
      	action.setParms({"item" : item});
        action.setCallback(this,function(response){
           	var state = response.getState();
            if (component.isValid() && state === "SUCCESS") {
                var items = component.get("v.items");
                items.push(response.getReturnValue());
                component.set("v.items", items);
            }
        });
        $A.enqueueAction(action);
    },

	
})

Nothing in the helper.

Thanks!
