DetailsView - One specific field is not being noticed on the ItemUpdating event

Here is the detailsView and below that is the code that I'm using to make sure that the fields are ALL being passed noticed on the ItemUpdating event. The final field, "Tech" is not being noticed as part of the DetailsView. I thought maybe it just wasn't picking up the bottom field, so I move the "Tech" field to the top of the DetailsView. Even then, "Tech" was not picked up by my C# code as one of the fields that was about to be updated.
