Answer 1

You have demonstrated the wrong side of the code, here is a part of the code that may help you (23699000 = account number, showdetalied procedure = calls a modal window, but you need to correct it for your task)

<div class="container" onclick="showdetalied('019');yaCounter23699000.reachGoal('CALL'); return false;">

I don’t understand how to generate the counter code, where it needs to be installed!
