[AccessD] Global Variable

Be aware of the fact that global variables lose their values after 
untrapped runtime errors.
In a runtime Access environment this is no problem (Access crashes... 
and has to be restarted)
In a full Access environment I have seen unpredictable result swith this.

You may want to get at them from a lookup table or set in a class.
