Hello,

I have two perl scripts that runs fine in the shell. But when I build a 
page with them, only in one case the results are shown in the other case 
i see a blank page.

I have done different test and I don't understand this issue. I don't 
know what i am doing wrong.

Follows the link to the code:
EURID script: http://pastebin.com/m3d6cbffe
ESNIC script: http://pastebin.com/m40755f40
PAGINA: http://pastebin.com/m5f8e1043

Thanks in advance to help me with this.
