syntax error

The error is on this line:

local choice, price, stuff = getShop(selc, data)

getShop is:

local choices = {}
    choices = {

    return choice, price, pixarr

I am so close to releasing this FTL like clone, this is almost the only thing left until I can release it D:)

i dont see anything wrong
can we see the full error and all the code before the error

The function that the getShop() is in:

local doShop(selc)
    local choice, price, pixarr = getShop(selc, data)
    if data.money - price < 0 then
        msg = "Not enough money!"
    else
        data.money = data.money - price
        if selc == 1 then
            if data.stats.health + 1 > data.stats.maxhealth then
                data.money = data.money + price
            else
                data.stats.health = data.stats.health + 1
            end
        elseif selc == 2 then
            data.stats.health = data.stats.maxhealth
        elseif selc == 3 then data.stats.armour = data.stats.armour + 1
        elseif selc == 4 then data.stats.damage = data.stats.armour + 1
        elseif selc == 5 then data.stats.accuracy = data.stats.accuracy + 1
        elseif selc = 6 then data.stats.speed = data.stats.speed + 1
        elseif selc = 7 then data.stats.wepspeed = data.stats.wepspeed + 1
        elseif selc = 8 then data.stats.health = data.stats.health + 1
        elseif selc = 9 then data.stats.evasivness = data.stats.evasivness + 1 end
    end
end

EDIT: nvm, I forgot to put function…

i can not emagine a more epic fail

elseif selc = 9 then
= is the assignment operator
not the equal operator
