[malugirl4]

I'm trying to finish this code..I'm still getting errors..can some plese help me!

Use indentation and line up your parenthesis. I think you'll see your problem(s) then!

What maze? You have a meandering robot only meandering in one general direction!

You start your robot on 0,0 but you don't prevent it from going negative! If it's at x = 0, you let it go -1 and beyod.

The robot never goes -y.

Look where the for loop 64 close brace is! And it isn't at the bottom of the code!

I'm not even sure how this compiles as you have else if's inside an if statement! Where's the close brace?
Same for the switch case, its an else condition, not in the main flow!

And other problems too! But start there, reformat, indent properly, line up your braces, and repost!
