Check if fielad A and fiel B both already have that value add a letter
I am still working on my bibliography table...
I have an Author field and a Year field... what I need is:
if that author has already a publication in the same year add an increasing letter to the year...
so I created a new field that should check if Author and Year already have that same information and if they do put an increasing letter to the field.
so if I have Tolkien, J.R.R., 1970, "The Lord of the Ring"
the next Tolkien's publication again in 1970 will be
Tolkien, J.R.R., 1970a, "The Sinmarillion"
and the next 1970's publication will be
Tolkien, J.R.R., 1970b, "The Hobbit"
is that possible???
