Collect data from a set of custom labels conversion of a specific page?

I need to extract the data conversion, in my case are clicks at different retailers, for a number of products. the nomenclature that I follow the following pattern and it is stored in a e.var:

website:campaign:retailer:product

I need extract the number of total clicks on retailers for each of the tracking codes for a specific campaign. A way I found was to create a custom variable that filters access to pagename (site) I'm measuring, filters the events containing retailers and counts the total number of instances by tracking code.

The problem I noticed is that when this is done, it counts the total number of instances of visits accomplished what I determined in the filter but also adds other interactions held.

Is there a way to consolidate only the instances I I filtered?

I hope it was clear but if they can help me and need any more information just write me.
