Issues with sending a consolidated email with multiple list items

Hi, 

 

I've sought reference from this article (url: https://www.c-sharpcorner.com/article/iterate-the-sharepoint-list-item-and-send-a-consolidated-email-to-the-recipient/) and followed the steps to create the sharepoint workflow that can send a consolidated email with multiple list items. 

 

Tested out the workflow - which seems to work fine with workflow messages logged till the step on counting the variable. However, my email is still not generated. Hence i believe i must have gone wrong with the LOOP logic. Still unable to pinpoint the exact issue. Please help.
