Hi Sheena,
First prefer lostfocus for validation (valid is more problematic).
Dateformat might not be in YYYYMMDD thus returning an emptydate better use strictdate formats and expressions as {^1900/01/01}.
Return dDate in valid is not a valid option. Return num or logical expression.
If you need to check only dates are not before 1900 then use year() to check.

* lostfocus
if year(this.value) < 1900  
* Is empty(date) allowable ? - If so add "and !empty(this.value)"
 nodefault   && Prevent focus to change 
 messagebox("You cannot enter a century before 1900")
endif
