you must debug the code to check tag values, because probably these tags are empty

quick example: lets suppose that you have an TAG.City="minoc", so you expect an event 'e_<TAG.City>_city' will be 'e_minoc_city'. But if for some reason the TAG.City is empty, the event name will be e_[nothing here]_city --> e__city

that's exactly whats happening on your code. An easy way to find these problems is debbuging the values, making it display the tag value somewhere (SAY, SYSMESSAGE, SERV.B, etc) just to make it easy to check if values are correct, like this:
this will make everything readable and easy to check if there's something wrong on this next line:
