Subject: regexp+hash problem

Hello !

I becoming totally mad about this simple script, whose goal is to 
capture various information (written in a single file) about some chess 
games : the conversion I need for the month seems to be the problem : I 
am using a hash to convert "Feb" into 2,etc. But, this works only for 
the first line of my file !?

The error reported is "can't convert String into Integer (TypeError)", 
but I can't figure what it means.

Can someone help ?
Thx
JC
