Topic awaiting preservation: simaple asp help

hi.

if i want to write a if statement in asp, and wan the write the null value, to i just put "" or "null"

can i write it as

if strFname = "" and strLname <> "" then {}

or i have to put the word null?

if strFname = "null" and strLname <> "null" then {}
?

thanx<:}

-

test for empty string
if variable = "" then

'do stuff

end if

test for null
if isNull(variable) = True then

'dostuff

end if

requested form variables are always empty strings if blank, database values will probably be nulls
