The first thing we need to do in this lesson (create a constrained variable of type `Int` with the name `num_1` and value `42`) is not working, even if I copy the code from the hint…

``````[Int]\$num_1 = 42
``````

If I put `[Int]\$num_1 = 42`in the first line of the script “variable_types.ps1” and run it, the first task box gets checked… bug should be solved anyways I’d say.
