I just bought two games today, 999: 9 Hours, 9 Persons, 9 Doors and some Yu-Gi-Oh games. (My one true weakness)

Anyway, I bought 999 cuz it seemed like a good puzzle/mystery game and it is PISSING ME OFF!! I'm stuck on the first puzzle!! I feel like such a loser . There's one suitcase that's red and another one that's blue. I found 2 keys that match each suitcase in color and now I have to enter a code in each, 4 numbers each. There's a paper with four triangles, 2 red and 2 blue. Also, there's a picture that has a number code based on the position of the triagle and whether it's solid of an outline. It said that there's red on the left and blue on the right and the key is to make right left and left right for the last two numbers, BUT IT WON'T WORK! I feel like I've tried every single combination. I even grabbed a piece of paper and started turning it around. AHHH, I feel so stupid!! It's only the first puzzle! Logic is failing me....

It's too new to look up a walkthrough. (I don't like cheating but it's been over an hour...) I need something to get me started...

If anyone has this game, PLEASE HELP!!
