I recently downloaded a game from FK's movies called Jiggy, it's a puzzle game with animated pieces. I wanted to created my own version with static images.

The games has radio buttons which give the opions of choosing how many pieces make up the puzzle (2x2, 4x4, 6x4, 8x6), the default is 4x4, I want to set it so that either the default is 8x6 or that it automatically goes to 8x6.

but I don't understand the code at all, I've never used radio buttons and they aren't like normal buttons so I'm lost! Could anyone please help? I have contacted the maker of the game but they haven't got back to me, the link is here:
