I found the problem, It was in the IB... there was not a connection from the column textField to the table view cell.

I know how I am going to proceed. I will build an array that I will update from the ComboAction and then use this array for the tableView as opposed to try to update the tableView cells directly.

Thanks Claude, I used the @IBAction because I needed the contents of the comboBox and I had tried the delegate before and could not see a way to get contents of comboBox.
