I too have grown tired of the incessant posting about how the tool is lacking when things don't work as you expect. That wouldn't be so bad if it were true or you were simply looking for enlightenment. Instead you continually gripe about what you perceive as shortcomings of the tool but the real issue is you put stuff together without "reading the manual". The latest is just another complaint about the same sort of thing - this time it's about using Date functions in table validation - an easily searchable subject that should take you 2 minutes to discover that it isn't allowed. Instead, the perception is that the tool you are using is so inferior to everything else you've used and it can't be that you aren't reading the assembly instructions for it.
Good luck. Signing off.
