Snap pairs memory game

Snap pairs memory game

I have reached a coding stall in my abilities, can anyone advise me on how to make this game come alive, I believe I've done enough so you get the idea of what I am doing, it should be simple right?

my code is here:

The game is simple, you select a number, one image pops up. You can select two numbers, if the images match, the numbers disappear. You need to find all the paired numbers.

Any advice would be great.

John.
