Hi. I want to add sub-task. Seems pretty simple, but every time I try to add it it says something's wrong and it can't be added. No further instructions.
Is there something else about the project that needs to be in place first for me to be able to do that?
Also, I want to make sure this sub-task type can be a child of Story and also a child of Task. How do I drag and drop that to be true?
