Test Variable?

[Phil Davis]

Hi Garrett,

When you declare a global within a handler, the data that goes into it 
will stay there, but no other handler can access it - the place where 
you declare a variable determines its scope. Put the "global" statement 
at the top of your script, outside of all handlers; then all handlers in 
that script can access it.

If your 'openField' handler is in a different script (like of a field), 
then that script will also need to contain a "global varCmdLineParamIn" 
statement for the var to be accessible there.
