Hi All,

I've been following a Tutorial on Apex Code development and what I'm looking to acheive is to provide a list of  order information from a custom object. The error I'm currently running into is:

Error: Unknown property 'ApexPages.StandardSetController.Location_ID__c'

My Controller:
 

public class InnovationOrderingController {
//ApexPages.StandardSetController must be instantiated
//For standard list controllers
	public ApexPages.StandardSetController orderdets {
		get{
		if(orderdets == null) {
			orderdets = new ApexPages.StandardSetController(Database.getQueryLocator(
			[SELECT 
			Additional_Comments__c,
			Construction_Type__c,
			Contract_Signed_Date__c,
			CSA_ID__c,
			customer_site_id__c,
			Location_ID__c,
			Order_Completion_Date__c,
			Order_Status__c,
			Order_Type__c,
			Product_Instance_Number__c,
			Requested_Speed__c,
			Requested_Start_Date__c,
			Service_Status__c,
			site_name__c
			FROM innovation_orders__c]));
	}
	return orderdets;
	}
	set;
	}
//Initalize orderdets and return a list of records
	public List<innovation_orders__c> getOrderDets() {
		return (List<innovation_orders__c>) orderdets.getRecords();
	}
}

My page:
 

<apex:page controller="InnovationOrderingController">
    <apex:pageBlock title = "Congration">
        <apex:pageblockSection columns="1">
        
            <apex:pageBlockTable value="{!orderdets}" var="order" >
                <apex:datalist var="o" value="{!order.Location_ID__c}"/>
                
            </apex:pageBlockTable>
        </apex:pageblockSection>
        
    </apex:pageBlock>
</apex:page>
