Would someone help me, I can't get to work the SX for controlling a hobby servo , I tried the PWM command, but its giving me some error that says "byte parameter expected"

what I wrote., well actually I used the template that comes in the help.

the idea of the project is to control a robot and to vary the times on each servo to make it move while the other servos stay in the same position..., I know I am far from that, but, well I gotta make 1 servo move first lol..
