IF...THEN won't let numbers to be summed

[flotulopex]

Hello,

I've had lots of help from many of you so I share my code for this SIMON game.

I wanted to make a hand-held SMD version of this game with 3 lifes and a level counter.

Start the game on speed-level 1 by pressing button n°1 (most left) and, respectively, press button n°4 to start on speed-level 4.

When you miss, the leds flash for the numbers of remaining lifes.

After you have used your 3 lifes, all leds flash 3 times and then you can read your score: most-right led counts the Units, second led starting from right counts Tens.
