on the code above i created a add counter
function patient_Callback(hObject, eventdata, handles)
counter2 = get(hObject, 'UserData') + 1;
set(hObject, 'UserData', counter2);
set(handles.Impt, 'String', sprintf('Number of Patients currently: %d\n', counter2));
but the minus code doesnt work
function patients_Callback(hObject, eventdata, handles)
counter2 = get(hObject, 'UserData') - 1;
set(hObject, 'UserData', counter2);
set(handles.Impt, 'String', sprintf('Number of Patients currently: %d\n', counter2));
guidata(hObject , handles);
What should i change to the minus code.

Impt_CreateFcn is missing.
For both patient_Callback and patients_Callback, you use
counter2 = get(hObject, 'UserData')
but notice that for patient_Callback, hObject is data attached to handles.patient, and for patients_Callback, hObject is data attached to handles.patients . You are not using the same data.
You should change patients_Callback to access handles.patient rather than hObject .
