I need help. I'm pretty much a beginner, and I need help in multiple areas. However I do have a particular question.

It depends on what you're doing. You have to change the FOR loop to match the amount of data you're reading. That FOR loop only works for 4 elements; if you have more, you have to change the range of the FOR loop. I'm not sure, but maybe DATA doesn't work if there are spaces between the lines. I haven't tried it; someone else will have to comment on that.

Are you the administrator? If so, what are the rules to joining contests and how often do they occur.

That's not uh... on topic lol. Your program just has to follow the submission rules, which are usually things like "can't enter an existing program" and stuff. Then you just have to submit it on time and to the right category. For example, these were the last contest's guidelines: https://smilebasicsource.com/forum?ftid=1465 They occur pretty much at random. It's usually on a whim or if people ask.
