Hello, I'm trying to add programmatically a second connection to the Scope block in Simulink, is there a way to do it ?

The error message:

Error using untitled4 (line 19)

Invalid Simulink object name: scope/2.

clc
open_system(new_system('test'));
add_block('simulink/Sources/Sine Wave','test/sine');
add_block('simulink/Commonly Used Blocks/Scope','test/scope');
add_line('test','sine/1','scope/1');
m = 0;
if m == 2
    product = add_block('simulink/Commonly Used Blocks/Product','test/prod');
    block1_handle = add_block('simulink/Commonly Used Blocks/Constant','test/const');
    line2_handle = add_line('test','sine/1','prod/1');
    line1_handle = add_line('test','const/1','prod/2');
    line3 = add_line('test','prod/1','scope/2');
    sim('test');
    open_system('test/scope');
    delete_block([product block1_handle line2_handle line1_handle line3]);
else
    b1 = add_block('simulink/Commonly Used Blocks/Gain','test/gain');
    l1 = add_line('test','sine/1','gain/1');
    l2 = add_line('test','gain/1','scope/2');
    sim('test');
    open_system('test/scope');
    delete_block([b1 l1 l2]);
end
