Hello

Perhaps someone can help me with a CGI written in perl that I am 
working on.

The script is taking data from a form which is user edited.  It 
is then
parsed or decoded, then looked up on a database file called 
ussaf.txt.
When a matching key is found, it is the entire database is copied
record by record into a new file, with the changed information.
  Then the newfile is renamed the old file.

I seem to be having trouble with the two opened files.
I am not being permited to open one file for reading
and another for writing.  When I get to the print DATAOUT
command, I'm getting an error message in the Appache log
as follows

Undefined subroutine &main::DATAOUT called at 
/var/lib/httpd/cgi-bin/add_lable.cgi line 27
<DATAIN> chunk1.
