Thank you so much.
I'll download now and try it.
UPDATE:
Ok so I have it installed but..
all customers have a red cross in the customer list. (the data is still in my db)
on the customer profile, the data does not save.
and lastly, the agecheck column isn't showing on the "Orders List" page
I have moved the agecheck to after email where its easier to see and don't need the date on the customer list so commented that out too.
The 18? column on this customer is Pass so should be a tick. Is the data in that column now a 1/0 option instead of Pass/Null
