Seeing as this was already not the problem I'll just comment for 
completeness' sake.

The backwhacking of the @ is only necessary in double quoted ("", qq{}) 
strings because otherwise Perl would attempt to interpolate the contents 
of an array named "@where".  If you have a piece of data that's come 
from another source (e.g. a form submission) the backslash isn't needed 
as it's not going to be processed by Perl again (unless you of course 
run it through some form of eval :).


An alternative if you don't need to interpolate anything else is to use 
a quotelike operator which doesn't do interpolation ('who at where.com' or 
q{who at where.com} for example).
