[Plugin: Top 10] How do I add to the counter?

Hello,

Loving the plugin so far. Here’s what I’m trying to figure out. I have a website that has an old counter value that I want to add to this new counter value. I was hoping I could do this in the php of the plugin by calling the contents of the custom field and adding them to the numerical vale of the top 10 counter, but all i’ve managed to get it to return is 0 or nothing when I change the code for the tptn_disp_count() function in top-10-counter.js.php

Any advice?

Thanks,
Evan
