That error is generated by the Carp Perl module.  It is placed in the browser for you instead of in a log file.  The only way to change the error is to change the code, in <a href="http://addbiblio.pl">addbiblio.pl</a> line 878, so that it checks the biblio loaded properly before calling the title function.  There, if the biblio didn&#39;t load, you can redirect to whatever page you want.<br>

Hello all.<div><br></div><div>I am having some problem with redirecting a standard KOHA Error to some other page. Actually I&#39;ve modified a function to navigate to next and previous biblionumber within the records in KOHA. The problem is that if I supply a existing biblionumber it works fine, but when I supply a biblionumber that is not present then it gives the following error.</div>
