Weird initial values using Serial

I'm using a serial communication to
read the values of 3 potentiometers. Now when the serial starts, the first values contain weird characters
which makes my processin sketch crash. I tried delay() on many spots but it's still giving wrong initial values

Am I missing something? Thanks!

Can you try in the Arduino IDE Tools->Fix Encoding and Reload? (You must save first your sketch). Regards.
