Complex datapoint - groovy script to calculate the value from the device property

You can't use ## in groovy.  I think those are reserved for PowerShell.  

Try something like this.  You can do hostProps.get or instanceProps.get depending on where the property is.

def answer = instanceProps.get("auto.myproperty123");
if(answer == "true")
{
    return "0";
}
if(answer == "false")
{
    return "1";
}
