if(undef($nomSQL)) { $nomSQL = "";} is probably not what you want. You are undefining $nomSQL, rather than testing for definedness. You probably want this: 

if( not defined $nomSQL ) {
    $nomSQL = '';
}

...also written as: 

unless( defined $nomSQL ) {
    $nomSQL = '';
}

[download]

...but the latter reads less clearly to me.
