how to call a function inside a table by a string?

so i kind of want my code to look like this..

local function something() -- make sure to put this inside a pcall() function
            local item 
            for i,v in pairs(slot:GetChildren()) do  -- gets item inside selected

                if v:IsA("Model") then

                    item = v
                end
            end
            func(item.Name)(item.Animation,slot.Name) -- item.Name == the func name


        end
        something()
    end

so basicly my idea is to put hole bunch of functions inside a script and when a player wants to use a item. it calls the function by the name of the item. for example if somone used a apple the script would find whats inside the slot (apple) and then call the function with its name and the arguments. let me know if this is kind of hard to understand and ill try to explain it better. thanks
