尝试对表格值进行算术运算

我正在尝试对性别选择更改名称（默认为男性）。但我做不到。我一整天都在尝试，但它仍然无法正常工作。 实际上它可以工作，性别从男性正确地更改为女性，但当我尝试将其更改回来（从女性更改为男性）时，我会收到错误提示：

[ERROR] *path*/cl_new_character.lua:1055: attempt to perform arithmetic on upvalue 'defMaleInfos' (a table value)
1. DoClick - *path*/cl_new_character.lua:1055
2. unknown - lua/vgui/dlabel.lua:232

下面是代码：

local defMaleInfos = {
    model = "models/kerry/player/citizen/male_02.mdl",
    name = randommname,
    surname = randommsurname,
    sex = 1,
    playerColor = Vector(1,1,1),
    bodygroups = {
        top = "polo",
        pant = "pant",
    },
    skin = 0,
    eyestexture = {
        basetexture = {
            ["r"] = "eyes/eyes/amber_r",
            ["l"] = "eyes/eyes/amber_l",
        },
    },
    hasCostume = false,
    teetexture = {
        basetexture = "models/citizen/body/citizen_sheet",
        hasCustomThings = false,
    },
    panttexture = {

    },
}

local infos = defMaleInfos

    bodygroups = {

        pant = "pant",
    },
    skin = 0,
