This appears to be a bug introduced in 2004 during the OS 9 to OS X
transition. It also appears in the saveas and saveacopyas statements,
and there is a related problem in the openfile statement (it can open
the wrong file if the volume is not available). I have fixed the bug for
the next release. In the meantime, here is a workaround:

if arraynotcontains(info("volumes"),"Public",cr())
    rtnerror "Sorry, Public is not currently mounted"
endif
Export "Public:Export folder:"+"Customers Data.txt",

Hmm, actually in a ..CloseDatabase procedure you would might just want
it to silently fail -- your choice. When the update comes out you could
control what happens if the volume is missing by using if error after
the export statement.
