That's where your completely wrong. I can see the error, calls to motor power
should be set out like this
motorPower128(1) = MyVariableName;
in this example the constant "1" means set the power to output B to the value
specified by MyVariableName. Output A would be 0 and C would be 2.
You may also need to add a line like
#include "C:\WINDOWS\Desktop\Lego\SWAN\swan.nqh"
but you'd have to rewrite it to point to your copy of swan.nqh.
Hope that helps.
