What am I doing wrong?

Hi All!

I am just jumping into the Unity world and have been reading a few books and following some tutorials but this project not let me off easy!

Everything to my untrained eyes looks good its a memory game so the user has to repeat the pattern of the buttons lighting up but at the minute it just seems to be skipping through the IF and logging "wrong"

Thanks, Jordan!
