Hi Beechey,
We will typically leave a post open unless the discussion goes way off topic, or someone resurrects a really old post by adding a new question to it. This way, if someone else has another solution to the same issue that they would like to add, or needs to ask for clarification about something, they can easily do so.
If one of the answers that is given to a question you post helps resolve the issue you are having, or points you in the right direction for resolving it, make sure to select that answer as correct and/or leave a comment under it indicating what additional steps you took to make that answer work for you.
Have a great day!
