I am trying to build my first Lightning Component for my production Org by following along with Trailhead and modifying my code to fit the data I need from my sandbox.  My component will not display and I swear I have been over my code 100 times. Any help would be great. 

Lightning Component

<aura:component implements="flexipage:availableForAllPageTypes" access="global" controller="DivisionHealthCheckController" >
    <aura:attribute name="Divisions" type="Division__c"/>
    <aura:handler name="init" action="{!c.doInit}" value="{!this}"/>
    <lightning:card title="Division Health Checks">
        <aura:set attribute="body">
        <table class="slds-table slds-table_bordered slds-table_cell-buffer">
            <thead>
               <tr class="slds-text-title_caps">
          		  <th scope="col">Division</th>
           		  <th scope="col">Grade</th>
           		  <th scope="col">Total Influencers</th>
               </tr>
            </thead>
            <tbody>
            <aura:iteration items="{!v.Divisions}" var ="div">
                <tr scope="row">
                    <td> {!div.Name}</td>
                    <td> {!div.Grade__c}</td>                
                </tr>
                 </aura:iteration>
            </tbody>               
          </table>
        </aura:set>       
    </lightning:card>	
</aura:component>

Controller

public with sharing class DivisionHealthCheckController {
    @AuraEnabled
    public static List<Division__c> divisionHealth(){
        return [SELECT Id,
               Name,
               Grade__c               
               FROM Division__c            
        ];
    }

}

JS Controller

({
	doInit : function(component, event, helper) {
        var action = component.get("c.divisionHealth");
        action.setCallback(this, function(data){
            component.set("v.Divisions", data.getReturnValue());
            console.log(data.getReturnValue());
        });
        $A.enqueueAction(action);
		
	}
})
