Hi Greg,
There is a simple fix for this. The problem is in the template
addbiblio.tmpl.
In the lines that call the javascript function AddField(), change from:
href="javascript:AddField(<!-- TMPL_VAR name="tag" -->)"
to:
href="javascript:AddField("<!-- TMPL_VAR name="tag" -->")"
I'm doing this from memory so I hope the placement of the quotes above
is correct!
This code needs to be fixed in 10 places (once per tab).
What seems to be happening is that the tag value is being sent to the
javascript function as an integer so leading zeros (as in the ISBN tag)
are being stripped.
