Tabs within Tabs Error

Hi, whenever I place tabs within tabs I get the following error:

Notice: Undefined index: aba_saida in C:\Program Files\NetMake\v71\wwwroot\scriptcase\app est1\Med_tabs\index.php on line 435

Line in Question (435) is:
$Saida = $_SESSION[‘sc_session’][$this->sc_page][‘Med_tabs’][‘aba_saida’];

can anyone assist?

Surely I’m not the only one to have come across this error?


I have this error too. The output is normal despite the error message.
