[AccessD] matching field error

Unless it is specifically set to null, a numeric field usually has a
default value of zero.  If you're dealing with numeric keys, this might
be tripping you up.

Hello Andy,

In the help function i saw what the error means. But it made no sence to
me. You say: "Is there any way they could have zeroes or zero-length
strings rather than nulls". When a field is empty i think there is
nothing in it. How can it be that a field is empty but a zero is
present??
