VBA Code: Select Records From Drop Down List

I have a spreadsheet that contains multiple rows per user. I need a combo or list box that pops up asking them to select their name from the drop down list. The list would be based on column A and would only include their name once.

When they select their name, the macro would then open the Form option from the Data menu, the Criteria button would be pushed and their name entered into the form, to return the first record their name appears on, then they could forward through the records, and update using the Next record button.
