Cannot Implicityly convert type 'object' to 'int'. An explicit conversion exists

I am trying to extract a cell from a row in a table and store it in a variable.  I thought I had defined everything properly but obviously I am missing something.  Can someone point out the obvious?

Here is the code:

int SelectedReferralQueueId;
        SelectedReferralQueueId = this.ReferralListWebGrid.DisplayLayout.SelectedRows[0].Cells.FromKey("REFERRAL_QUEUE_ID").Value;--------------------squiggle line under the word "this"Start Free Trial
