Compiling Problem

Hello all:

When I try to compile the drivers for this board, I get these messages:

Arduino: 1.6.5 (Windows 7), Board: "Arduino Nano, ATmega328"

INA3221_test.ino: In function 'void loop()':
INA3221_test:46: error: 'busvoltage1' cannot be used as a function
INA3221_test:62: error: 'busvoltage2' cannot be used as a function
INA3221_test:78: error: 'busvoltage3' cannot be used as a function
'busvoltage1' cannot be used as a function

Any idea of what is going on?

Also: What are these instructions trying to accomplish?:

loadvoltage1 = busvoltage1  (shuntvoltage1 / 1000);

Thanks in advance for your help.
