# Common Problems

### *There isn't an enumerator for my submodule.*

The main module only has enumerators for submodules that existed at the time the version was released. If there isn't an enumerator, just put the exact name of the submodule when you attempt to get it, or install a newer version of the main module.

```lua
local mod = RegisterMod("TestMod", 1)
local IsaacHelper = require("testmod.isaac-helper.init")
IsaacHelper.Init(mod, "testmod.isaac-helper")

local PlayerTracker = IsaacHelper.GetModule("PlayerTracker") -- This works!
```
