I am wondring why <> and is not not working only = is working
i tried everything still not working
I created a demo and the <> operator works as expected. Below is what demo code looks like. If you are still having trouble then share enough code to reproduce your issue. Use descriptive words to describe what is happening in the
code. "Not working" tells us nothing.
