Pist gta5 online?

Moin, I play online on the ps4 gta5. So, my question is: I'm about to rob my own casino, but I can't get any further. I chose the variant of big fraud, every time I have a team and go to the casino, I can't get any further. I always have to chop into something with a finger, and that's exactly where I screw up. I have no plan how to do it, I saw a video about it, and took my fingers off it. But every time I type it in and press triangle to check it is wrong. This really sucks, can someone help me somehow?

You have to compare the lower fingerprints with the big one. The parts must be found somewhere in the entire print
