Changing array names creates error

I was looking for some parts to build a form and found one that's almost what I need - thanks mehmetcik. What I'm having an issue with is that the array can be renamed and still work just fine, but changing the list items causes an error. In the examples the first two run just fine (as long as all references to the array are changed also) but the third example causes an error and I am at a loss as to why. The problem workbook is attached.

MyNames = Array("Employee", "Equipment", "Part", "Defect", "Lot")

MyOtherNames = Array("Employee", "Equipment", "Part", "Defect", "Lot")

MyNames = Array("Somebody", "SomeEquipment", "Part", "Defect", "Lot")
