I wondered if someone would mention that, but didn't want to drift too far from the point, which was the "prior to call is_null()" part of Lester's sentence was redundant, since the problem was entirely unrelated to is_null(). Regards, -- Rowan Collins [IMSoP]Correct, there is no way of testing for that full stop. There is, though, not sure if already mentioned: array_key_exists(“var”, get_defined_vars()) && is_null($var)if the variable does not exist there is no way of testing for that state prior to calling is_null()
