UserForm to Return the MAX date in a TextBox resulting from VLOOKUP in ComboBox

[infinity]

Finish it with the likes of:
ApptDateTextBox.text = iif(MaxDate=0,"",MaxDate)

(Untested)

THAT DID IT!!! Thank you very much! However I have no idea what the "IIF" is, that is the first time I have seen that. Either way, thank you for your help!
