Hi to all,
I have a question about using expression "null" in condition.
I am checking for empty sharepoint column.
When I use the condition like this, everything works fine and when the field in the sharepoint list is empty, the condition goes true, when there is any value the it goes false.

But when I try to use the condition like this, it always goes false. Am I geeting it wrong and it could not be used like this?

I'm checking for multiple columns and I need to find the first one which is empty and put some value in it. I had no problems from the start, but as the number of columns started to grow, I needed to add some condotions and when I tried to use six in row inside IF condotion the Flow stops giving me the options as you can see bellow. So I needed to devide the conditions and that is why I need to use "is not equal to NULL"

Thank you for your advice.
Michal
