Need to customize error statements in form

[mfmathes]

I created a database for obtaining customer information at a trade show. The entry form is set to Pop up. Entry in data fields is required. I set a macro at the end of the entry form, "New Record Macro" to save the record and then to GoToRecord to create a new blank form for the next person to fill in. When a field is left blank, an Access error screen pops up. Then a Macro Single Step error screen pops up. I need to replace these pop ups with customized directions. I'd like to completely eliminate the Macro Single Step error. I have no experience in Visual Basic. I am using Access 2010.

It's an excellent intro to Access 2010.
