How do I enable a disabled script in Workspace via Dialog choices?

Pls help I'm new to scripting. This is the script i put in the Dialog and it doesnt work

local dialog = script.Parent
local activateScript = game.Workspace.["MyDisabledScript"] --Name of your script


dialog.DialogChoiceSelected:connect(function(player, choice) --This is for getting the service when the choice is selected
    if choice == script.Parent.DialogChoice.ChoiceA then --Choice A is what you named the option in studio
        --Do what you want to do
        activateScript.Disabled = false --Activated Script


    elseif choice = script.Parent.DialogChoice.ChoiceB then
       --Do what you want
    end
    --Repeat for all choices
end)

Is it in a local script? DialogChoiceSelected needs to be in a localscript.
