Use the error message as the title of your forum post
If you want help on this forum and you can find an error message, then it is the most useful and informative title you can have for your forum post.
Before posting, start by searching for keywords in the error message to see if you can find a previous solution. If you can find a thread which has exactly the same error as you and that solves your issue, click like on the post that helped you. If you still need help, post to that thread instead of making a new one.
If you do need to make a new thread then start with the error message but replace references to specifics with generic terms.
For components, use the default name for that component, e.g. movie.
For loops, use trials (the default loop name).
For resources, use the name of the resource type plus the extension, e.g. movie.mp4.
For spreadsheet variables, use S.
For other variables, use x for floats, i for integers, a for arrays and d for dictionaries.
Make sure that the post itself contains the unedited error message.
