Hi newsgroup

In my excel form I have a textbox where a date value can be entered. When I
enter a wrong value excel crashes.

Now I like to validate this entry with some kind of entry mask. I like to
verify that the entered value cannot be someting other than a date?

Is there a possibility to do this in excel?

Thanks alot
