I got an error of undefined variable, but I did not find the with small letter toolbox\_title, but I found 4 files with TOOLBOX\_TITLE showing the variable.

```auto

Undefined variable: toolbox_title

```

Can anyone please explain what type or error am I dealing with?

I got this issue with MAC 2024 version, but same code is used on 5.2.2 than it work smoothly. Is it new developer issue or what type such issue fall into ?

Hi @Vimsrocz ,

It seems to be an issue in `tbx_build_help_loader` function. We will fix it in next Scilab version. Until then, can you try to define the `toolbox_title` by adding `toolbox_title = TOOLBOX_TITLE` in your `builder.sce` file (it may make your code work)?

Not really

```auto
//

mode(-1);
lines(0);
function main_builder()

    TOOLBOX_NAME = "spacecraft_gnc_tbx";
    TOOLBOX_TITLE = "Spacecraft GNC Toolbox";
    toolbox_dir = get_absolute_file_path("builder.sce");

    // Check Scilab's version
    // =============================================================================

    // check minimal version (xcosPal required)
    if ~isdef("xcosPal") then
        // and xcos features required
        error(gettext("Scilab 5.3.2 or more is required."));
    end

    // Check modules_manager module availability
    // =============================================================================

    if ~isdef("tbx_build_loader") then
        error(msprintf(gettext("%s module not installed."), "modules_manager"));
    end

    if ~isdir(toolbox_dir+filesep()+"images"+filesep()+"h5")
        [status, msg] = mkdir(toolbox_dir+filesep()+"images"+filesep()+"h5");
        if and(status <> [1 2])
            error(msg);
        end
    end

    // Action
    // =============================================================================

    tbx_builder_macros(toolbox_dir);
    tbx_builder_help(toolbox_dir);
    tbx_build_loader(TOOLBOX_NAME, toolbox_dir);
    tbx_build_cleaner(TOOLBOX_NAME, toolbox_dir);
endfunction

if with_module("xcos") then
    main_builder();
    clear main_builder; // remove main_builder on stack
end

```

Can you please point out? Where to add, as I added last and multiple position, but it is not working? Can you please point out, and we can talk or personal message me, so I can give you accesses to resolve issue fast?

Error is

```auto
Undefined variable: toolbox_title

```

`toolbox_title = TOOLBOX_TITLE` must be inserted before calling `tbx_builder_help` and it may work.
