Because you don't feed CInt() with an integer

^^^^^^^^^^^^^^
Those aren't integer!
May be you're trying to convert an ASCCI to its DECIMAL value in the
ASCII table: Asc("x")
You can't ask a converter to convert "x" or "-" to a number: they are not,
so it is not possible.
And once for all, NULL is NOT a value: it is... NULL, so it need a separate
processing: IsNull("something")
SELECT CASE iRain
CASE IsNull(iRain)
' Do something
CASE IsAscii(iRain)
' Do another thing
...
END SELECT
