Object statistics in Visual Tool

Greeting,
I'm trying to get some basic data from a simple model. There are two itemtypes that get processed and then leave the system. All I'm lookig to get is to display the cumulative count for each type in a visual tool. Any hints would be appreciated. Attached model using version 6
Thanks

Visual Display: Text
Text Display: Display Label Value Text

Increment a number label for each itemtype on a trigger

inc(label(obj,"your number label"),1);

obj is a pointer to the object storing the label (e.g. current)

If you want to display two values, modify the source code to read a second label and add this value as numtostring in the text string.

Reset the number labels to default values.
