@aselder ah thanks.
I'm new to elixir so I can't fully understand how I'm supposed to properly fix the errors, but for each of the variables updated in the if statements, I get the following error -
variable "label" is unused (if the variable is not meant to be used, prefix it with an underscore) // same for inputs_classes and wrapper_classes.
So in case of errors, they don't get updated with form-control-danger class.
Edit - using Elixir 1.10.4 on windows 10

This is awesome! Thanks.
Looks like there might be one typo on L10. I believe the class should be
form-control-danger
notform-control-dange
.
