I have gui wherein I need show information from table When I open gui, I have this error: "attempt to index a string value with bad key ('Index' is not part of the string library)"

SH file. In this file I put table information

MyList = {}
MyList = {
    Index = 1,
    Name = "Name 1",
    Class = "exampleclass",
    Description = "Desc 1",
    Model = "modelname",
    Color = Color(255, 255, 255, 255)
}

CL file. This file contains the part of the code where the error occurs. The error occurs on the first line

for k, v in SortedPairsByMemberValue( MyList, "Index" ) do
    if v.Class == "exampleclass" then
        local mainbuttons = vgui.Create( "DCollapsibleCategory", category )

        mainbuttons:DockMargin(0, 6, 0, 2)

        function mainbuttons:Paint(w, h)
            local h = 24
            surface.SetDrawColor(v.Color)
