Hi,
I'm getting this error when I build (Glinks 3.1.0):
Use of uninitialized value in division (/) at /home/qango/public_html/cgi-local/dir/admin/Links/Import/S2BK.pm line 121.

Schematic for the file:
- Newline delimiter is changed to \0 (hex and ascii 0).
- Each line starting with '\\\\' starts off a new table.
- The first line following the '\\\\' is the table name by itself (NOT prefixed).
- The first character of the line after that is the delimiter for that table, and
the rest of that line is the columns of the table delimited by the delimiter.
- All subsequent lines (until another '\\\\') are individual records.
- All fields (headers and records) are escaped where needed in '\\XX' format
(where 'XX' is the hexadecimal representation of the character).
- All lines until the first '\\\\' are treated as comments and are ignored.
- Everything following '\\\\' is treated as a comment and is ignored.

I noticed this on another thread, but there was no resolution posted.
Any idea what's going wrong or how to fix it?
