MatLab GUI accelerometer reading DATA

Hello, as of right now i'm trying to read in accelerometer data to my MatLab gui thru a pushbutton.. So far here is my code
function pushbutton6_Callback(hObject, eventdata, handles)
%mapping between analog inputs and X,Y,Z axes.
% Xch = 1;
% Ych = 3;
% Zch = 2;
fprintf(out.s,'R');
%read voltages from accelerometer and reorder
reordered(1)= fscanf(out.s,'%u');
reordered(2)= fscanf(out.s,'%u');
reordered(3)= fscanf(out.s,'%u');
%determine what offset and gain values to use
offset = calCo.offset;
gain = calCo.g;
accel = (reordered - offset) ./ gain;
%map analog inputs to axes
handles.gx = accel(1);
handles.gy = accel(2);
handles.gz = accel(3);
guidata(hObject, handles)
This code was partially written for me. I'm trying to understand it since i've only been using matlab for 3 weeks. Can anybody help me what i'm doing wrong? I have a button for calibrating and a button for reading in the serial, but as of right now i'm trying to read actual data and later graph.
THANKS
FIrst problem fixed... scroll down below for the new problem I cannot seem to fix.. THANKS

Note: the lines
guidata(hObject, handles);
handles.gx= 0;
handles.gy= 0;
should have the assignments before the guidata() call.
