Is it a etiquette or requirement that every answer needs to be verified before being posted? In one of the questions here : How can i use Now as a time filter in reports?, I saw that the question got a spontaneous please verify before you post your answer. Even though it was not in any derogatory intention, is this a part of what needs to be done/ good to do !!!!
As I was the one who received that response, I'll say that I did indeed test that formula before posting it. Apparently, I didn't test it in the proper context because the Report Editor did accept it when I edited an existing report!:(
Afterward, I tested it again in a new report in a different context and it wouldn't accept the filter formula. So, my bad in that sense.
All I can say is that we're all human and sometimes we're going to post things in response to a question that either we've misunderstood the context of (easy to do here), misread, or made an error of some kind when posting our response to it. At the same time, that's also one of the many reasons multiple answers can be posted here.
