Hi!

I have a userform in Excel (version 2000) which has a textbox (txtInvoice)
and a listbox (lstInvoices).

When the user, after typing the invoicenumber into the textbox, presses the
Enter-key (on the numerical keypad) the number should be added to the
listbox.
How do I assign the sub that does the transfer to the Enter-key?

TIA
PO
