Hi,
I am having trouble with my Visualforce page and Apex Class. Everything seems to be fine apart from the error Unknown Property 'NFOSDisplayDivisions2Controller.Division_Space2__c'. I can't seem to figure out what is going on, could someone please help me out. Thank you.

Apex Class:
public with sharing class NFOSDisplayDivisions2Controller {
    
    public List<DivisionWrapper> listDivisionWrapper{get;set;}
    public List<Division_Space2__c> selectedDivisions{get;set;}

    public NFOSDisplayDivisions2Controller ()
    {
            listDivisionWrapper = new List<DivisionWrapper>();
            searchRecord();
    }
    
    public void searchRecord()
    {
        listDivisionWrapper.clear();
            for(Division_Space2__c a: [select Id, Name,Number_of_Competitors__c, Availability__c, RecordTypeID ,Active__c from Division_Space2__c limit 30]) 
            {
                listDivisionWrapper.add(new DivisionWrapper(a));
            }
    }

    public void processSelected() 
    {
        selectedDivisions = new List<Division_Space2__c>();
        selectedDivisions.clear();
        for(DivisionWrapper wrapDivisionObj : listDivisionWrapper) 
        {
            if(wrapDivisionObj.selected == true) 
            {
                selectedDivisions.add(wrapDivisionObj.acc);
                // Here you can add the counter or you check the selectedAccounts.size()
            }
        }
    }

    public void ActivateData() 
    {
        for(Division_Space2__c acc : selectedDivisions )
        {
            acc.Active__c= true;
        }
        update selectedDivisions ;
        searchRecord();
    }

    public void DeActivateData() 
    {
        for(Division_Space2__c acc : selectedDivisions )
        {
            acc.Active__c = false;
        }
        update selectedDivisions ;
        searchRecord();
    }
    


    // This is our wrapper/container class. 
    public class DivisionWrapper 
    {
        public Division_Space2__c acc {get;set;}
        public Boolean selected {get;set;}
        public DivisionWrapper(Division_Space2__c a) 
        {
            acc = a;
            selected = false;
        }
    }
