Hi All,

I have a visualforce page that displays counts of results. The results are calculated from a list of records, based on a selections from the user. I had to split the controller class into 2 due to the number of characters limitation. In the visualforce page i have controller="Recruitement_Dashboard_Controller1", how do i get the results calculated in the second controller class to display? Please see the code below: (i have posted stripped down examples of my code, i need the returned results of all the methods in both classes, where the data list is generated in the first class)

public class Recruitement_Dashboard_Controller1{


Public Transient List<Invite_Tracking__c> invitetracking;
