When casting to an Integer don't forget it will loose any floating point value, so 5.0 becomes 5 which according to above will display a message. 5.0a will cast to 5, 5.5a should also cast to 5, but might be rounding the wrong way? a5.5 will cast to 0. -- Best regards, Richard Davey http://www.phpcommunity.org/wiki/296.html
