Sorry, perhaps I should clarify. I forgot to use the drop down year box, just inserted the exact year in the bottom as it appeared to suggest I could, but got an error. Hit the back button - as instructed, and it reset the form, so all blanks.
Entered the name again, this time with a year range and searched again, the name didn't appear - why? because it had reset my choice of marriage back to baptism. Hit the back button again and of course all reset again.
Third time lucky. The database itself is probably excellent but the manner of searching could be improved on I think, in comparison with other similar search sites.
