Don't you mean integers?

[psrpinto]

I do mean strings. Using integers presents problems since there's a maximum value that can be stored. I still need to research more about this subject but for the moment I'm convinced using strings is the way to go.

Any thoughts?

I see, we use int(11) which is not a problem for us because we do small money transactions.
