About Listbox_easy4u but hard4me

I have tried to solve my problem about listbox for many hours but I didn't solve it yet.
the problem is when I select the first item on listbox 1 (blocked by blue colour), I wanted at the same time, the first item on ListBox2 and ListBox 3 are selected and blocked by blue colour too.
These the codes :

tbSel = ListBox.GetSelected("L1");
if tbSel then
ListBox.GetSelected("L2",tbSel[1]);
ListBox.GetSelected("L3",tbSel[1]);
end

...the problem is when I select the first item on listbox 1 (blocked by blue colour), I wanted at the same time, the first item on ListBox2 and ListBox 3 are selected and blocked by blue colour too.

Try this On Select Event ListBox1:

-- Make sure multiple selection is disabled in all List Boxes.

-- Get the indexes of the items currently selected in the listbox.
selected_items = ListBox.GetSelected("ListBox1");

-- If there were items selected in the listbox, display a dialog with their indexes.
-- If no items were selected, display a notification message.
if (selected_items ~= nil) then
    output = "";
    for index, item in pairs(selected_items) do
        output = output..item.."\r\n";
        if item == 1 then ListBox.SelectItem("ListBox2", 1) ListBox.SelectItem("ListBox3", 1)end;
        if item == 2 then ListBox.SelectItem("ListBox2", 2) ListBox.SelectItem("ListBox3", 2)end;
        if item == 3 then ListBox.SelectItem("ListBox2", 3) ListBox.SelectItem("ListBox3", 3)end;        
    end    
    Dialog.Message("Selected Items", "The indexes of the selected items are:\r\n\r\n"..output);      
else
    Dialog.Message("Selected Items", "There are no selected items in the listbox.");
end

Hope it helps.
