Error in seo and shin program

The error Nested procedure definition G0155 means that there is a procedure inside of a procedure, like this:

// Start of procedure
proc (1) = hypotenuse(a, b);
    local c, a2, b2;
 
    // Start of procedure definition INSIDE
    // another procedure definition which is an
    // illegal 'nested procedure definition'
    proc (1) = square(x);
        retp(a .^ 2);
    endp;
 
    a2 = square(a);
    b2 = square(b);
    retp(sqrt(a2 + b2));
endp;

Does your code have a nested procedure definition like this?

yes I have in my code a nested procedure:

        zxi = x[(i-1)*(t)+1:i*(t),.]; // (t)xk

It is possible that I missed it, but I do not see a nested procedure. I see a few procedures, but each of them is defined separately. They all open with the proc statement and end with the endp statement.

Do you see the difference between the nested procedure I wrote earlier, where a new proc is started INSIDE another proc, compared to yours where there are just a few separate procs?

Do you have the link from which you downloaded this code?

this is the link, the program is named invest03.prg.zip

I still have the same error and i don't know why? I can understand that is not a nested procedure but how can I fix this ?
