I didn't see anyone else reply so here is some template code (very wordy to be clear) that should get you going...

Custom Condition
 
# Get the transaction object
my $TransObj = $self->TransactionObj;
 
# Make sure the transaction is a Comment before we check anything else
unless ($TransObj->Type eq "Comment") {
  return 0;
}
 
# Now get the custom field value for our transaction
my $TransCustomFieldName = "TransCustomFieldName";
my $TransCustomFieldValue = $transObj->FirstCustomFieldValue($TransCustomFieldName);
 
# Log it for debugging
# NOTE: I always log with the queue name because I may use the same type of routine in multiple queues
$RT::Logger->debug("$self->TicketObj->QueueObj->Name: $TransCustomFieldName = $TransCustomFieldValue");
 
# return 0 unless our value changed
return 0 unless ($TransCustomFieldValue != 0);
                                               
1;

Preparation Code

Clean-up Code

my $TicketObj = $self->TicketObj;
my $TransObj = $self->TransactionObj;
my $QueueObj = $TicketObj->QueueObj;

# First get the current value of our Ticket Custom field we want to update
my $TransCustomFieldName = "TransCustomFIeldName";
my $TransCustomFIeldValue = $TransObj->FirstCustomFieldValue($TransCustomFieldName);
# Make sure to normalize your Transaction Custom Field Value if needed (in this case it isn't but if you are processing multiple Transaction Custom Fields it may be)
# if (!$TransCustomFieldValue) { $TransCustomFieldValue = 0; }

# This code looks different because it is pulled right from the Wiki with some simple modifications. Best to keep the same structure for maintainability.
my $CFName = "TicketCustomFIeldName";
my $CFValue = $TicketObj->FirstCustomFieldValue($CFName);
# Make sure you normalize your Ticket Custom Field Value too
if (!$CFValue) { $CFValue = 0; }
 
# Or whatever you want to do with it...
$CFValue += $TransCustomFieldValue;
 
my $DefaultValue = '0';
my $RecTransaction = 1;
$RT::Logger->debug("$QueueObj->Name: $CFName -> $CFValue");

my $CFObj = RT::CustomField->new($QueueObj->CurrentUser);
$CFObj->LoadByNameAndQueue(Name => $CFName, Queue => $QueueObj->id);
unless ($CFObj->id) {
    $CFObj->LoadByNameAndQueue(Name => $CFName, Queue => 0);
    unless ($CFObj->id) {
        $RT::Logger->debug("$QueueObj->Name: $CFName doesn't exist, Queue - " . $QueueObj->Name);
        return undef;
    }
}
my($result, $msg) = $TicketObj->AddCustomFieldValue(
                    Field => $CFObj->id,
                    Value => $CFValue,
                    RecordTransaction => $RecTransaction
	);
unless ($result) {
    $RT::Logger->debug("$QueueObj->Name: Couldn't set $CFValue as value for CF $CFName : $msg");
  return undef;
}
 
1;
 
NOTES:

1. Make sure you change the TransCustomFieldName variable to your actual field name
2. You may have to change the check to see if your field value changed. For my type of field in this scrip it was simple enough to do the test I'm doing. (Also, I'm a Perl newb so don't think this is pretty Perl.)
3. Make sure you change the CFName variable to your actual field name
4. Make sure you normalize your TicketCustomFieldValue variable just in case it hasn't been set yet. Additive values are never fun when you start with an unknown
5. MUST BE TransactionBatch
6. Use at your own peril, I haven't tested this code and it is freely given to the public domain as-is, enjoy!

I hoe that helps.

Thanks,

Mike
