This is a question that I think I have the answer to but someone may know a better way of doing it. I have an if-do-else statement block. I want to say that if a certain cloud folder path already contains users input then do nothing, else add in the users input to this folder path. The way I have done this is to say "if - does list [FOLDER PATH] contain [USER INPUT] - do - (_I have left this blank_) - else - in list [FOLDER PATH] add at last as [USER INPUT]. Is this good practise or is there a better way to do it? ---

Yes, it’s fine to leave part of an if/else block blank. If you prefer, you can use the `not` block in the Logic drawer instead. ---
