error trap for required field

[Guest]

Hello,

I have a subform bound to a query. The subform is continues.
On the subform is a field, for this field the option required is set to yes.

When I leave this field blank when I leave the record. I get this error
message.
"The field cannot contain a Null value because the required property for
this field is set to true. Enter a value in this field"
So everything works like I want it.
But the question is: How can I trap this error so that I can replace it with
one in my own language?
Which event triggers this message?

Use the Error event of the form to catch these engine-level error messages.
