Runtime error 3075

I have a form where the user selects a name from a combo box and it
populates the form. On this form is a subform that allows a user to
enter and view memo's of individual records.However if the user does
not select a name from the combo box and simply clicks the view memo
button then I get the runtime error message. I understand why I get
the message but I need help working around it.Is there any way to make
the user choose a selection from the combobox first (combo76), or
ensure that the memo button is unavailable unless there is a record
present.

TIA
