Yes, this error happens when using the spoiler brackets than the code brackets in a forum such as this. Code that needs special indents require a structure, and if its not there, whether the code is good, it will fail. Notice that when you open the spoiler box, all the code is flushed to the left. Where in the original code, some of the code should have been tabbed (indented) a bit right.

Perhaps we should start using the code brackets when presenting such work in the future. Avoid the spoiler bracket.
