trying to get 2 separate values in alert box

Question

On my error message both inspStartTime.StartTime & inspEndTime.EndTime end up being the same values returned.  Although they each belogn to a different textbox. Any clues?
 
[CODE]
           for (int i = 0; i < VisualTreeHelper.GetChildrenCount(myVisual); i++)
            {
                // Retrieve child visual at specified index value.
                Visual childVisual = (Visual)VisualTreeHelper.GetChild(myVisual, i);



                // Do processing of the child visual object.
                if (childVisual is TextBox)
                {
                    MaskedTextBox btn = (MaskedTextBox)childVisual;
                    //Check first to see if the element is null
                    if (btn.Tag != null)
                    {

                  

                        inspStartTime = new InspectionTime();
                        inspStartTime.TimeID = Convert.ToInt32(btn.Uid);
                        inspStartTime.StartTime = btn.Text;
                        
                        inspEndTime = new InspectionTime();
                        inspEndTime.TimeID = Convert.ToInt32(btn.Uid);
                        inspEndTime.EndTime = btn.Text;
                       
                     

                       // updateMileage = Convert.ToInt32(StartTime.Text.Trim());
                       // updateMileage = Convert.ToInt32(EndTime.Text.Trim());


                        {
         control.ShowErrorMessage("Litte Test." + inspStartTime.StartTime + " " + inspEndTime.EndTime,  MessageBoxImage.Exclamation);
                        }
[/CODE]
