Kevin gave the solution to change:
 @array = split(/-/,$CGI->{from});
in
 @array = split(/\0/,$CGI->{from}); 

What confuses me in this is that above you say that you have returned the 
sql string from this perl block and with that you got a correct query. 

Perhaps Kevin can shed a light on that one aswell?  I'd think that you would 
not be able to have done a split with the - , so there would not have been a 
correct sql query in the first place? Or is there something magic going on? 

CU,
