Hi Jaime,

PHP automatically declare variables so I cannot realize why this error is happening ...[/quote]

Ahh, this isn't strictly true - there are certain circumstances that I bump up against in CI a lot more than 'raw' PHP (and it's been so long since I've used that, that my memory about it may be flaky) where you do get errors if you try to use a variable before setting it, even to an empty string say.
