Bracketing your example with <code> and </code> 
if ($Session->{'usrType'} eq 'Pro') and 
    ($Session->{'usrSystem' =~/SEF/VAL/SUM/SAR/MRT/ALB/MRE/VER/RML/AUS
+/ORG/MSX/BAR/LAS/)
{do something}

I can see several typos. It should look like: 
if ( ($Session->{'usrType'} eq 'Pro') and 
    ($Session->{'usrSystem'} =~/SEF/VAL/SUM/SAR/MRT/ALB/MRE/VER/RML/AU
+S/ORG/MSX/BAR/LAS/))
{do something}

You should always use use strict; use warnings; If there's still a problem, have you considered displaying the values of $Session->{usrType} and $Session->{usrSystem}?
