I have code like this: 
my $login_tot;
my $campaign_tot;
my $work_tot;
foreach my $func ('login','campaign','work') {
    # do some things
    my $tmp = calc_difference($var1, $var2);
    # update _tot vars here
}

[download]
What I need in the "foreach" loop is a way to update the "_tot" variables. I have tried things like:

${$func . "_tot"} += $tmp;

[download]
or 
my $ref = "$func" . "_tot";
$$ref++;

[download]
Not working, so I don't understand how the indirection or referencing works. Any ideas on how I can get a clue??
