How to call a simulink file from push button of GUI?

Hi,

I prepared a GUI includes radio groups for different selections. Finally it has a RUN button and I expect to run a tractor_semitrailer.mdl file with pushing this button.

I defined 3 switches in simulink which are changing by radio buttons, key1, key6 and key7. Thus I need them for running the simulink model and they are the strings.

In push button function I used str2num for keys, Chenged them to num and save with new names but there is a problem "Error while evaluating DestroyedObject Callback"

% --- Executes on button press in runtag.
function runtag_Callback(hObject, eventdata, handles)
key111 = evalin('base','key1')
key11 = str2num(key111)
key666 = evalin('base','key6')
key66 = str2num(key666)
key777 = evalin('base','key7')
key77 = str2num(key777)
keymm = evalin('base','maneuver_type')
keym = str2num(keymm);
TSoutput = 92;data;main;state_space1
sim 'tractor_semitrailer'

Would you please give me some hints?
