[Nant-users] Calling Environment functions

[Devin Grant]

I have the release version of NAnt (build 0.85.1720.0) on my machine and I am unable to call “${environment::variable-exists(temp)}”.   Error message: Property evaluation failed. _expression_: ${environment::variable-exists(temp)}                                                                                ^^^^     Property 'temp' has not been set.   The “temp” variable exists in my system environment.  Can someone please help me figure out what I am doing wrong here?   Thanks,   -Devin
