Display Text In A Cell

irst Problem:

I need a little help with the same employee time sheet that I am working on in Excel 2007. I have a dropdown box in Cell E1 that lets the employee select their name. Example, if the choices in the drop down are: Smith, John Jones, Paul Nelson, Bob and Hall, Bill. So the names are Last Name, First Name. Once the employee chooses their name, I would like Cell G1 to display "Hello (E1). Welcome to AA Company." (where E1 is the employee's name but First Name Last Name - so it is reverse order of the choices in the dropdown). If E1 is left blank, I would like Cell G1 to display "Hello. Welcome to AA Company."

Second Problem:

How can I get rid of #VALUE! in a cell without messing up the formula of that cell or the cell it corresponds to??
