Timer function can't find objects

I am using a timer function, but it cannot find my objects. I have a simple GUI with two text boxes (edit1 and edit2). The timer function is calling findobj('tag','edit1'). It usually finds the handle the first time the timer runs, but on all further instances, the findobj call comes back empty.

I am using R2014b. Code is below. Any clue as to what I am doing wrong?

Thank you, Steve

function varargout = TimerTest(varargin) % TIMERTEST MATLAB code for TimerTest.fig % TIMERTEST, by itself, creates a new TIMERTEST or raises the existing % singleton*. % % H = TIMERTEST returns the handle to a new TIMERTEST or the handle to % the existing singleton*. % % TIMERTEST('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in TIMERTEST.M with the given input arguments. % % TIMERTEST('Property','Value',...) creates a new TIMERTEST or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before TimerTest_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to TimerTest_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)". % % See also: GUIDE, GUIDATA, GUIHANDLES
