In my Database 'Movies' in the table 'Lent' there is an 'ID' Field with autoincrement and another Field 'Number'.
I'd like to count all entries in a field 'Name' or in 'ID' (e.g. 10 entries in 'ID')
In the add page I would like to have in the field 'Number' the value 11 (10+1), when I load the page.
is this possible ?
(sorry of my bad english)
