HI All

I’d like to add custom python function to be computed on my report, but I stuck with common known error:

"'NoneType' object is not callable" while evaluating 'testme()'

I’ve checked this forum and other tutorials and I can’t see any mistake in my code, but for sure there is one. Could you be so kind and point what I am doing wrong?
