Create siumlink model using script.

I am trying to build a script that will create a simulink model taking the input block data from excel.

However facing difficulty in addressing the created block. i have read my data using code

%Read from Excel and open a simulink block
[~, signal] = xlsread('Com Simu mAPPNG.xlsx')
new_system('test');
 open_system('test')
 count= size(signal,1);
% create bus with number oif input as count.
 add_block('simulink/Commonly Used Blocks/Bus Creator', 'test/BC1');
 set_param('test/BC1','Inputs','count'); 

This works fine. When i enter the loop to create blocks names from the data read from excel (create memory read blocks).

or x=1:count
     add_block('simulink/Signal Routing/Data Store Read', 'test/MemoryRead1', 'MakeNameUnique', 'on');
     set_param(gcb,'Name', signal{x,1}); 
     set_param(gcb,'Datastorename', signal{x,1});

This also works.

Now i want to add line. and to address the block

     add_line('test','signal{x,1}/1','BC1/x');

Gives error

Invalid Simulink object name: signal{x,1}/1

Pls help how to address these variable.

src_signal = signal{x,1} + "/1";
dst_signal = "BC1/" + x;
add_line('test', src_signal, dst_signal);
