Hmm. You should really be using a text editor (e.g. Notepad++) for writing, scripting & saving your work, and a browser only for test-running the game as a “player”. The first 3-4 pages of the Basic Tutorial on the Wiki should help to explain “what you need to do” things a big better:
No problem, glad to help. You might also want to keep an eye on this forum topic and maybe even bookmark the CSIDE website itself so you can download & try a copy as soon as it’s released. It completely replaces the usual editor / browser setup so all your writing, coding & testing (including Quicktest & Randomtest) takes place in one neat package, as well as offering many other advantages such as superb project management and much easier & simpler file handling.
