Customize Error Messay

Hello all:

Thanks for all your numerous help.
I posted this earlier, but got no response, your urgent help is required.

I usually get 2 error messages on my form.

When I set up the table, I made the date field mandatory. The first error message, error 3314, "The field 'Memo.Date' cannot contain a Null value because the required property for this is se to True. Enter a value in this field"

I would like to change this error message to:
"Enter Date of Memo"



The second error is:
Microsoft Visual Basic
Run-time error '490':
Cannot open the specified file

End Debug buttons.

I would like to change this error message to:
"The file does not exist/it has not been previously saved."

And I don't want the End or Debug buttons to show.


Thanks for your help once again.
